Femap 11.2 Overview




Preprocessing Contact Manager Data Surface

Data Surface Interface to contact setup •   Show/Hide by Location •   Change Property •   Highlight Selected



Preprocessing Element Thickness

Element Thickness to the element nodes/corners •   Previously all thickness data were

stored on the property record

•   Tapered plates required one property per element – many property records

•   Specifying corner thickness data on the element record allows just a single property to be referenced




Tapered Shell elements now can all reference the same PSHELL property record •   Modify, Update Element, Adjust Plate

Thickness/Offset command is best way to create tapered shell elements with element thicknesses

$ Femap Property 1 : PLATE Property PSHELL 1 1 .1 1 1 0. CQUAD4 1 1 1 2 12 11 + + .15.1555556 .15.1444444 CQUAD4 2 1 2 3 13 12 + + .1555556.1611111.1555556 .15 CQUAD4 3 1 3 4 14 13 + + .1611111.1666667.1611111.1555556 CQUAD4 4 1 4 5 15 14 + + .1666667.1722222.1666667.1611111




Modify | Update Elements | Adjust Plate Thickness/Offset updates •   New Element Thickness option in Update section to assign thickness to element corners

instead of using values from property, while Property Thickness option retains legacy method to create required additional properties

•   Added Top At Nodes and Bottom At Nodes options for Element Offset •   Added Reset Element Thickness

button to remove thickness from element corners of selected elements and revert to element thickness values defined by the property

•   Added Reset Element Offset button to quickly remove planar element offsets from selected elements



Preprocessing Midsurface Enhancement

Modify | Update Elements | Midsurface Thickness and Offset •  Allows selection of Midsurfaces created using Geometry | Midsurface |

Automatic or the elements on those surfaces, then applies the appropriate thickness and offsets to the elements to match the original geometry.

Midsurface Geometry Meshed with plate elements of any thickness

After Command – Offsets only After Command – Offsets and Thickness



Preprocessing CBUSH Enhancements

Spring/Damper element updates •   Added CSys and From Property options to Orientation section, with CSys allowing the

user to select a Coordinate System from the drop-down directly on the element, while From Property uses the legacy method of getting Coordinate System ID from the selected Spring/Damper Property (Orientation CSys)

•   Added Location and From Property options to Orientation section, with Location allowing the user to enter a value for Spring/Damper Location directly on the element, while From Property uses the legacy method of getting the Spring/Damper location from the selected Spring/Damper Property (Spring/Damp Loc)




By moving the Orientation Coordinate System to the element itself, a single spring/damper property can be used to specify stiffness on multiple coincident node CBUSH elements which require different orientations

•   Organize any number of output sets into an analysis study

•   Easy to find, delete, or operate on all output sets from a single analysis run (for example, collect all time steps from a transient analysis)

•   Control whether studies will be automatically created and how they are titled in File Preferences




Analysis Study Manager - Accessed via Model | Output | Create/Manage Analysis Study menu command or Manage command in context sensitive menu for Analysis Studies in Model Info Tree •   Create a New Analysis Study or

Update an existing study

•   Result Data Creation options create new virtual output sets •   Create All Immediately: all data needed for combination / envelope sets are

created immediately and stored in the database (longer initial creation, faster results display)

•   As Needed / Temporary: all data needed for combination / envelope sets are created on-the-fly (faster initial creation, potentially longer display time)




Results Set Processing Data Surface: Linear Combinations & Max/Min/Max Abs Value Envelopes

Postprocessing Freebody Section Cuts

New Section Cut freebody display mode •   The user defines a cutting plane in the

model and the contributing freebody nodes and elements are determine automatically

•   Total summation location can be placed at •   Plane/path intersection •   Nodal centroid •   Static location

•   Nodal and total summation vectors can optionally be aligned tangent to the path without having to create additional coordinate systems




Freebody Section Cut modes Plane: Cutting plane is defined via base point and normal vector. Path is defined as the normal vector; cutting plane will always be normal to the path Plane / Vector: Similar to Plane, however an additional vector is defined for the path. The cutting plane will always remain co-planar to the original plane and does not have to be normal to the path Vector: Cutting plane is normal to the defined vector. Path is the defined vector; cutting plane will always be normal to the path

Curve: Cutting plane is normal to the tangent vector at a point along the plane. Cutting plane will always be normal to the tangent vector

Freebody Contributions From – Nodal Summation contribution – Reverse Values •   The Nodal Summation freebody

contribution can now be reversed •   This is the value calculated by the

solver that is the summation of the solver calculated contributions (non-rigid elements, SPC, MPC, and applied), not the summation calculated by Femap

•   Imbalances, such as glue and contact forces, can be treated as a contribution by reversing the sign



Charting Vector vs. Entity, Relative Positioning

X-Axis Values for Vector vs. Entity Data Series can now be specified as a position relative to a node or element in the model •   Select “Position” for the X-Axis value

and enable “Relative to” option •   For nodal vectors, the position is

relative to the selected node •   For elemental vectors, the position

is relative to the centroid of the selected element



Charting Vector vs. Entity, Relative Positioning



Charting Grid Line Colors

Grid line colors can now be controlled by the user •   Color for both X and Y axes is controlled via

a single setting •   Minor gridlines are automatically assigned

a complimenting color •   For charts with dark backgrounds, the

specified color can be automatically adjusted for easier visibility

•   Femap line styles specified in the color are observed in the grid lines

put them •   Use MSC MARC reserved nonlinear data vectors to store nonlinear results Connection Regions •  Improved performance of expanding connection regions in certain cases. For

example, model with 692 regions and 400,000+ solid elements previously took ~9 minutes to write a Nastran file, now takes ~4 seconds (135 X performance increase)

Spaceball or any 3-D Mouse •   Updated Femap code to respond to driver changes which caused problems,

some of which caused Femap to become unresponsive. In short, the drivers now send significantly more move messages, at very short intervals that could cause problems (fixed for 11.1.1 or 11.1.2)

•   December 2014 – During Femap internal testing, discovered another issue in Spaceball drivers, worked directly with 3DCONNEXION and most recent driver has been corrected on their end as well
