A. COMMENTS – VERSION NUMBER
VER Version number for datas
Datas can still be given in the 7.2 format. IVER distinguish between old and
new formats. If IVER <80, file is formatted to the old format. If 90 > IVER
>80 , file is related to the 82 format. If IVER > 90, file is related to the 90
format. When old datas are used, FINELG creates a ".DAN" file with datas in
the new format.
ICOL column width for data definitions (4, 5 or 6)
The column width of datas can be determined on base of 4 columns (4 columns
for integer datas, 8 or 12 columns for real datas), on a base of 5 columns (5
columns for integer datas, 10 or 15 columns for real datas) or on a base of 6
columns (6 columns for integer datas, 12 or 18 columns for real datas)
All datas are given below with the 4-definition. The complete 5-definition is
given in italic in the synthesis of cards.

IMKL Use of MKL libraries for linear system solution
0 : No use of MKL
1 : Use MKL with default parameters
2 : Use MKL with user-provided parameters. An IMKL card must be provided.
(see chapter B.g)
Default : 0
NB: the MKL conditional bit-wise reproducibility (CBWR) can be
activated by setting the IMKL value to its negative counterpart (-1 or -2). This
enhances reproducibility on multiple processors or different machines but may
degrade performance.
Remark: UFO and ULO are necessary when one uses cross-section data base (see "FINITE ELEMENTS") or
residual stress pre-established schema, or concrete material data base or wind loading.
Remark: in general, the use of MKL libraries should considerably reduce both computation time and memory
consumption. However, this feature is still under development. Do not hesitate to contact the R&D team in
case of unexpected behaviour. Set IMKL to zero in case of trouble.

REPP Step number for restart.
Number of the step in the sequence REPS from which resolution is restarted.
If REPP=0 , restart is done from last converged step.
IALLO use of dynamic allocation
0 : yes
-1 : no
in case of dynamic allocation, temporary savings for elements are maintained in
RAM memory. if IALLO = -1, savings are done in temporary files. IALLO=0
is faster but needs more RAM memory.
LISDDL List of the dofs of the system
List of the dofs used for resolution.
For example, for a plane frame, u,v,ɵ displacements are active.
so LISDDL=1, 2, 6 =126.
IDR Useless
IDW Private storage unit to save the displacements.
They are saved at all steps for graphic output;
Test : 1 ≤ IDW ≤ 4
IDW=1, 2, 3, 4 corresponds to file DE3,DE4,DE5,DE6.
IRE Index for renumbering.
IRE=0 renumbering with default values of the parameters.

KARA Index for computing/printing of reactions.
0 compute and print.
N compute, but print only at node N.
These options are also valid if NOM = -1.
KREQ Index for printing of residuals forces.

KALT = 3 : stop after K control (after VERK);
KALT = 4 : stop before K solving (after REAK);
KALT = 5 : stop after K solving (after SOLK);
KALT = 6 : stop before stress computation (works only if NOM = -1).
TDEB Beginning of the time evolution of the program.
T0 is the beginning time of the resolution. If no time sequence is defined, time
remains constant and equal to T0. Time is defined in days.

SR, SW = 1,2,3,4 corresponds to files .RH1, RH2, RH3, RHF.
Optional: The default value is SR = 1 and SW = -2.
Tests: SR = 0 if no RESTART.
Note : On unit 4, FINELG saves automatically the current last executed
step, provided that :
- The step is not saved on SW by INT or SAV(i) (see card c).
- The step is not the last one with INT = 0.
To suppress this automatic saving on unit 4, give SW < 0.

ITERAM Maximum number of iterations by step
If traffic lanes only.
This number depends on the convergence criterion. Normally, the convergence
must be reached in 15 iterations. In most cases, it is reached in 6 iterations but if
the coefficient is bad or the convergence criterion too severe, the convergence
may be not reached. So, it's better to limit the number of iterations. If the
convergence is not reached, the iteration stops and the results are used as there
were converged. The non-converged steps can be detected in the LOG file.

ICHMO = 0 all modes are used.
ICHMO = 1 only modes in the list defined in the next card.

Notes :
- the three types of data cards are mixable provided for a given node :
E.1 data precedes E.2 data.
- the definition of node coordinates may appear more than once a time, only the last one is valid.
- if several initial deformations are defined at one node, its value is equal to the sum.
- for a given node : repeated E.1 data cancels previous E.2 data.

Coordinate generation
KOR < 0 allows a coordinate and node numbering generation to be performed.
In the first card, the first node of the series is given, and KOR 0 defines the selected coordinate system.
In the second card, the last node of the series is given, and KOR is the number of spaces between the first and
last nodes, where KOR is given a negative sign to recognise a generation.
The generation proceeds along the three coordinates ; the generated nodes are regularly spaced and numbered
from the first to the last node.
Note that a "KOR < 0" card may follow another "KOR < 0" card ("successive lines").
E.b Initial deformation by nodes
- Coordinates increments are given here for chosen nodes.
- Coordinate system may be chosen at each node independently of the one used in E.1.
- Generation on successive lines is possible like in E.1.
- Surface generation proceeds line by line between corner nodes NA, NB, NC;
the choice and the order of NA,NB,NC is not neutral !
- Three types of generation are possible :
linear : D = DA + (DB - DA) ;
sinusoïdal : D = DS sin () ;
semi-sinusoïdal : D = DS sin (/2) ;
with D any coordinate X, Y, Z and a non-dimensional coordinate equal to 0 at NA and 1 at NB.
- Three types of interpolation are possible :
cartesian : by polygonal length, s ( = )
defining cartesian increment DX, DY, DZ
cylindrical : by angular length ( -A)/(B -A) ( = )
defining radius increment, must be in increasing value,
B - A > 2 is accepted (helix).

One card defines a typical local coordinate system referred to by LAX (corresponding line in the array of local
axes).
The cards may be put in any order (array !).
LAX Identification number of local axes LAXa or LAXb.
NA, NB, NC Guide node numbers (warning : different of beam K node).
Z, Y, X Angles of the three successive rotations (in degrees).
A local coordinate system at a node N (node number is given on supports cards) is defined:
- either by three nodes, called GUIDE NODES,
- or by three successive rotations X, Y, Z.
In the first case, one has :
local x axis : x⃗ = (NA)(NB)
local z axis : z = x⃗ × (NA)(NC)
local y axis : y⃗ = z × x⃗
Guide nodes NA, NB and NC may be nodes of the structure. Their coordinates must given.
In the second case, the three angles are defined by three successive rotations. Such a technique is difficult to
use, except in the case where there is only one rotation, for example in two-dimensional structures. As such
structures generally lie in the XY plane, the angle Z is given first in the "LOCAL AXES" card.

E.f Initial Deformation By Files
These cards enable the introduction and combination of structure deformations given by displacements files
(see Saving in B.c.-). For normalisation, see E.3.
NDI cards define NDI deformations to be read and combined (in any order). Combination proceeds by simple
addition with individual multipliers on each component.
NFIC File number (private storage unit number).
If left blank, NFIC is considered to be identical with its previous value.
At each file, corresponds one NFIC value.

NPAS Number of the saved deformed shape to be read in file NFIC.
If left blank, NPAS = 1.
FACX/Y/Z Component multipliers.
If FACX = FACY = FACZ only FACX is necessary with NPAS < 0.
Test: not all zero !
- Displacements files must be of same number of unknowns than present analysis (see B.-b.-).

E.h Roughness and Hunting
The data relative to the vehicle's movements about the bridge are of two kinds : the roughness and the hunting
phenomenon.
E.h.1 Roughness
ITYR = 1 for a roughness definition
L The number lane of circulation
LY The number sequence of roughness
A number of sequence of roughness is applied to some circulation lanes and are superimposed. Each
sequence is composed of a pair of values for X and Z saved in a file.
The here-above card show that the sequence number LY is applied to the L lane with a translation X0 along
the Xd axe of the deck.
LY is equal to 1, 2, 3 or 4 that indicate that the data of the sequence are saved in the files *.RY1, *.RY2,
*.RY3 or *.RY4.
L equal 1 to n where n is the number of circulation lanes.
X0 indicate that a translation in the local axes of the deck; Xd = X0 + X is considered as the coordinates in
the local axes of the bridge.
Remark
L cannot be applied two times to the same circulation lane
The same number LY can be applied to different lanes, these lane have the same roughness.
E.h.2 Hunting
ITYR = 2 for a hunting definition
L The number lane of circulation
This number cannot be repeated to the same lane, otherwise the repetition is null. The
hunting movement is applied to two lanes at maximum.
Only, the first two lanes are taken in account.

A maximum of two cards is possible for two circulation lane
if A = 0, the hunting movement is null
E.h.3 Files *.RY1, *.RY2, *.RY3 and *.RY4
(X,Z) are couple of points defining the roughness
The couples must be in increasing order against X
Z1 equal to zero except we want to have a shock
The couple of points are generated by the program RGHNSS

If they are more than 12 nodes, they must be continued on a second card in the
same field, that is, [16X, 12I4], 12I4 for 12 nodes.
i increment node layer.
When elements have two identical layers of nodes, and when the node numbering
of one layer can be obtained from the other simply by an increment i (i 0), only
one layer and the increment i (i in columns 65-66) can be declared. Be careful
when using this technique !
See example on the left.
m Automatic generation indice for index data.
See below "m : automatic generation...", at the end of this section.
Index field
IDEM Index for identical elements.
0 new element ; standard option;
1 the element is geometrically and mechanically similar to the previous one (same
TYPE, IMEC and IGEO);
2 moreover nonnodal loads and load cases and, possibly, residual stresses are
similar to the previous element.
Notes: In the first card, IDEM = 0.
Advantage of IDEM 0 : corresponding node coordinates are not necessary and
need not be defined (see E.-; economy!).
IDEM 0 is not possible if all nodes coordinates are defined.

8 : Element generation in one direction.
9 : Row generation in the other direction.
Note : A "j=8" card cannot follow a "j=9" card.
A "j=9" card should follow a "j=8" or another "j=9" card.
KMEC increment for IMEC numbering.
it may be negative.
KGEO increment for IGEO numbering.
it may be negative.
Be very careful when using KMEC and/or KGEO, especially in the row
generation.
KSTEP Increment on supplementary data of node field.
Optional : → if not given, then KSTEP = 0.

Any index can be easily modified.
Indices can also be created by such cards, which may be easier than the direct use of the indices, especially
when element generation is used.

About the automatic generation of the nine last indices S to IKT
m Index value for automatic generation of indices
The value m must be defined in the first element card and its value defines the generation mode of the 9 last
indices :
m value the generation
blank proceeds before F3.- data
A proceeds after F3.- data
G - only proceeds during the element generation
- the indices of a generated element are equal to the first
element of the generation (equal or not to zero)
- proceeds befor F.3. datas
S is suppressed, all indices must be defined
A summary of the possibilities of the element generation and indice generation is presented in the examples
here on the left.
The effect of this generation should be carefully examined ! A control is obtained by the printing "OK
ELEMENT" which shows the actual set of indices used.

F.d Residual or Initial Sresses or Strains (RISS)
One card of integers defining the type of RISS and the affected elements followed by one to six cards of
floating point values describing the state of RISS.
An element number cannot appear more than once in all the cards M1.
Not available for all types of elements : see "FINITE ELEMENTS".
F.d.1 Type of Riss and affected elements
KODES Indices to define the state of residual stresses.
1 to 6 codes in a conventional order defined by the state of stress (or possibly
stress resultants, i.e. internal forces) in the element
for beams trusses:
See "FINITE ELEMENTS" for proper definition and values of KODES
for plates, shells membrane:
each KODE corresponds to a component of stress or strain.
0 zero component;
1 non-zero stress or strain component ; the strain is transformed into a stress by a
one-dimensional stress-strain law (POISSON's ratio ignored);
2 non-zero stress or strain component ; the strain state is transformed into a stress
state by a two- or three-dimensional stress-strain law (POISSON's ratio
considered).
Test : 1 and 2 KODES cannot be combined in the same card.
Remark : The number of non-zero KODES defines the number of M2-cards below,
except if m = ± 1 or m = ± 11, in which case only one M2-card will be enough.
m Treatment type of RISS.
> 0 "live" RISS, giving rise to a constant load case ;
if NOM = -1, load case = 3 (possibly added to other loads);
if NOM -1, load case = 1 (added);
< 0 "dead" RISS; the resultant stresses are simply added to the stresses arising
from loads (without equilibrium or plasticity check).
for beams, trusses :
See "FINITE ELEMENTS" for eventual proper definition and values of ³m³,
for plates, shells, membrane :
1/11 → constant m 10 stress input
2/12 → linear RISS on the element
3/13 → quadratic m 10 strain input
mm generally not used (see below).

F.d.2 Numerical values of RISS
If m = ± 1 or ± 11, 1 to 6 components are given on the same card in accordance with the non-zero KODES; →1 card.
Otherwise, to each non-zero KODE must correspond one card ; the ith card must correspond to the ith non-zero
KODE (no mixing !);
For plate, shells, membrane :
- if m = ± 2 or ± 12, n values are given for the n corners of the element, following the same order as for the
nodes ;
- if m = ± 3 or ± 13, n values are given for the n points of the element, following the same order as for the
nodes.
The total number of M2-cards must be 6.NCI.
Remarks
. RISS data are particular to each kind of element ; therefore, always see "FINITE ELEMENTS" for
complementary information.
. If the RISS state of stress is elastic, either RISS stresses or strains may be given.
. If it is initially elasto-plastic, preferably give the RISS strains (if stresses are given, not the actual stresses are
used, but those deduced elastically from the strains; this avoids the indeterminacy in case of an
elastic-perfectly plastic stress-strain law, see figure on the left; naturally, these "wrong" data will be
transformed into correct ones by the program!).
. If the RISS state of stress is initially elasto-plastic, and has to be considered as an initial elasto-plastic state
of the structure from the very beginning, then put mm = 100.
. Do not forget that if
NOM = -1 and m > 0
residual stresses enter the load case no.3 (it may be necessary to define a fictitious load case no.1). If m < 0,
they are added to the stresses of the load case no.3 (without entering any load case).

G.a Loads
G.a.1 General Analysis
One card defines a typical imposed load or displacement referred to by ISOL (corresponding line in the array
of loads and displacements). The NSOL cards may be put in any order (array!).
ISOL Identification number.
xF xu, Load or displacement components,
which must be in accordance with the dof sequence available at the nodes.
If more than one card is needed, use -ISOL (negative value of ISOL on the previous card) as identification
number on the continuation card.
See additional information in § G.2.- below.
G.a.2 Seismic spectrum analysis
A special use of the load cases cards is the definition of a seismic spectrum. Spectrum is defined by a basis
spectrum, multiplied by acceleration factors in the 3 directions of space. In this case, one ISOL card defines
the basis spectrum, and one card defines acceleration factors
G.a.2.1 definition of the basis spectrum
ISOL Identification number.
Ti, ab Point of the basis spectrum
Ti : period
abi : basis acceleration
The basis spectrum is defined by discrete points (Ti, abi). Between these points, a linear
interpolation is used.
G.a.2.2 Definition of the acceleration factors
ISOL Identification number.
Mx,My,Mz Multipliers of the basis spectrum
Mx : Multiplier in the x direction

ISOL1, ISOL2 Identification of the load cards
For usual loads and for masses, only ISOL1 is used
For spectrum analysis :
ISOL1 card of definition of basis spectrum
ISOL2 card of definition of acceleration multipliers
Then, total acceleration in direction j for mode k is defined by :
ajk = Mj ab(Tk)
For ITIP = 558 :
ISOL1 card definition for IDOF
ISOL2 charge number in the *.ACG file
For turbulent wind analysis :
ITIP=-4 :
ISOL1 card of definition of wind
ISOL2 card of definition of damping
ITIP=-40 :
ISOL1 card of definition of variation of structural damping
This card is optional.
Remarks
If CC and/or ITIP and/or ISOL are left blank, they are considered to be similar to their previous value ;
therefore, they cannot be zero in the first card.
The cards may be put in any order.
A repeated NODE or ELEMENT number means that the same force is applied as many times (valid only for
forces, not for other types of loads!).
If a local coordinate system is declared at a node, component of nodal loads (ITIP = - 1 or 1) must be given in
this local system.
Linear stability analysis (NOM = -2 or -3) computes eigenvalues which are multipliers of all given loads (so be
care: dead weight is multiplied).

H.d Imposed load levels
F(k) k = 1,10 Imposed load or time levels
Combined with an automatic loading strategy or with the arc-
length, these values enable to obtain results at imposed load multiplier.
For time sequence, imposed time is T+F(K), T the beginning time of the sequence.
Note : to impose to obtain result at level equal to zero, one must give the following
imposed load level different from zero.
All imposed load levels are automatically printed on listing and/or saved for
SELFIN
Remark : All these load levels are automatically printed (saved for SELFIN)
IMPORTANT REMARK
- In case of arc length method : Sequence is stopped when last imposed level is reached except for the last
one.
- When no imposed level is defined, loading is stopped for a total increment equal to 1 except for the last
one

K. EVOLUTION OF STRUCTURE
These cards define the evolution of the topology of the structure within time. From definition of initialisation
time of elements, time and load sequences are defined in such a way that every element is created in a load
sequence.
The use of this kind of resolution needs to :
- define a first load sequence in which dead weight case is incremented to its nominal value
- define a suit of load and time sequence til the end of construction phases.
Program will mix sequences for creation of elements and sequences defined by the user.
EVOL cards are divided into 2 groups :
- ELEM cards which define elements creation and disparition
- MONT cards which define derrick position
GPPAA, GPP33A, PPC33A, GTSA, CONLIA, RESSA , RESS2A, RESSPA, POUSSA can be used to
modelize a plane evolutive structure.

NOTE : GENERATION OF LIST OF NUMBERS
A series of numbers in arithmetic progression may be given under the form
[3 I4] M -K N
where M and N are the first and last numbers and K the increment.
This type of generation is available for :
cards B.c. : savings and printings
cards F.3. : modification of element indices
cards G. : duplicata nodes
cards J. : load cases
cards K. : supports
cards M.1. : residual or initial stresses or strains.
However, in one card, the total of all numbers, when series are expanded, must still be less than or equal to
NUMMAX !
