Beam Section LibraryCreate Beam Property by Library : This function is visualized and

convenient for users to create beam property.

Beam Section LibraryUsers can select different Beam Section Type.

The Beam Section library includes: AISC, CISC, EURO, INDI, USER.

Define the dimension of the Beam section.

The property of the Beam section is calculated according to Section Dimension.

Topology Mesh Automatically average or merge all inner nodes on two boundaries if their first and last nodes have been averaged or merged.

BEFORE

RemeshThe command will re-mesh the shell using the new mesh size, replacing

the existing elements and connecting them to the surrounding mesh.

Increased/ decreased the nodes by clicking number using the left or right mouse.

Adjust the re-mesh regions

Change the nodes on the free edge based on new elements size.

2 Line meshTick on Line Segment to combine the multiple line segments as one side

Once user selects two groups line segments as two sides, program draw up the side 3 and 4 using dotted line automatically

Drag Mesh

Source element type is 1D/2D

Create 2D elements from existing line elements;

Create 3D elements from existing 1D/2D/3D elements.

The element type of target element

Drag Mesh

Solid faces are selected

When source element type is solid

Linear Mapping

Select source/target elements

Automatically or manuallyselect 3 nodes respectively from source/target elements

Distribute layers as requested

Create solid mesh by mapping the mesh from the source shell to the target shell.

Linear Mapping

Create Arc

Split the original line at the end of the created arc.

Split Original LinesSplit Original LinesCombine Lines

Split the original line at the end of the created arc.Combine the arc and the split lines.

Split Surface

Split by Surface Intersection add the new option:

Split Both – All the target and splitting surface are

split.

Split into four surfaces

Sweep Surface by LCSLCS an be used to define the sweep path.

Define LCS

Set the sweep distance and direction.

Set V axis of LCS as the path

Align NodeIn old version, users are allowed to select only one line to align nodes. After updated, multiple lines are supported.

Project NodeMore project direction are supported:

BY LCS: The direction can be U\V\W axis of LCS;

By Vector: Define the direction by 2 nodes/points

By Surface Normal: The direction is the Normal of the target surface

Change/Add offset of Beam Element

The keyword of beam in Ls-dyna is*ELEMENT_BEAM_OFFSET

Keyword Option: wx2, wy2, wz2

Keyword Option: wx1, wy1, wz1

Assign Beam Properties

Input the new Mass

The average mass of selected elements

This feature can help the users to modify the Mass/SPH Element mass in bulk.

Assign Mass and SPH Property

Create SPH element on the center of selected Shell or Solid element

Create SPH Element

Transform Element

The shell elements’ normal are adjusted when elements are mirrored.

ConnectionA new connection toolbar instead of spotweld toolbar.

New Feature in this toolbar:

The spotweld generation speed are significantly improved.

Connection-create

Supports MAT100 spotwelds in solid

elements, 4/8/12/16 Hexahedron elements

can be created.

Support adhesive type of connections

Num of layer

Link part ID

Connection-connector

The connector include weld points and glue area, the operations has:

Can be listed and edited by Connected List;

Can be retrieved from spotweld.

Enhance Selection Method -by Spread

Spread for selection is used in conjunction with selecting.

When spread angle is X(X>0),the visible nodes on the faces which normal angle is less then X will be all selected.

Create Group from SetAllows users to create group from part set.

Right click Part on model tree

select Create Group from Set, PreSys will create Group for each

*SET_PART automatically.

Toggle on *INITIAL_VELOCITY, PreSys will display the nodal velocity vectors for translational velocities and rotational velocities now.

Rotational velocity is shown

Display about Node Set

PreSys only shows the nodes in the set for the

displayed elements/nodes/parts currently now.

Default Folder of Save/Save AsWhen Save/Save As and Exporting a model, the default folder will be the folder where the current model file comes from.

Add to PartIn new PreSys, most functions will give selection to users to decide which part they want to use.

If the using part are invisible, there will be a tip in the message window. Users will no longer complain that they can't find the elements they just created.

3 selection

If the part is visible, there is a tick in the box.
