New Feature in 2012 R2
Preprocess
Shape Mesh / Box MeshGenerate the box constituted with shell elements or hexahedron elements.
Box by Points: Select several Points to create box boundary, PreSys calculates the largest space in X,Y,Z-Axis .
Box by Region: Create box mesh in defined LCS.
Shape Mesh / Box Mesh
Define the box parameters in LCS
Generate the Cylinder constituted with shell or hexahedron
elements.
Three Cylinder types for user to select.
Cylinder: Define Vector Normal by Two Nodes/Points or by LCS.

Generate the Torus constituted with shell elements or hexahedron elements.
Two torus types for user to select:
Full Torus
Shape Mesh / Torus
User Controlled.

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.

Solver Path
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.

Re-space Boundary Node
Add Washer
Drill Holes option allow user to
drill a new hole into the mesh
where has no hole.

Select Holes option allow user
select the rectangular holes to
create the washer.
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.

Model Check
The 1D, 2D and 3D check functions are reorganized.More criteria are provided for 3D element check.
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.
