1 New Feature in 2012 R2

2 Preprocess

3 Shape Mesh / Box Mesh Generate 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.

4 Box by Region: Create box mesh in defined LCS. Shape Mesh / Box Mesh Define the box parameters in LCS

5 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. Shape Mesh / Cylinder Mesh

6 Circular Truncated Cone Shape Mesh / Cylinder Mesh

7 Cone Shape Mesh / Cylinder Mesh

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

9 User Controlled. Shape Mesh / Torus

10 Beam Section Library Create Beam Property by Library : This function is visualized and convenient for users to create beam property.

11 Beam Section Library Users 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.

12 Run Analysis (NISA) Analysis Control

13 Run Analysis (NISA) Run Analysis Working Folder Solver Path

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

15 Remesh The 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. New element size

16 Remesh Re-space Boundary Node

17 Add Washer Drill Holes option allow user to drill a new hole into the mesh where has no hole. Add washer

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

19 2 Line mesh Tick 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

20 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

21 Drag Mesh Solid faces are selected When source element type is solid

22 Linear Mapping Select source/target elements Automatically or manually select 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.

23 Linear Mapping

24 Create Arc Split the original line at the end of the created arc. Split Original Lines Combine Lines Split the original line at the end of the created arc. Combine the arc and the split lines.

25 Split Surface Split by Surface Intersection add the new option: Split Both – All the target and splitting surface are split. Split into four surfaces

26 Sweep Surface by LCS LCS an be used to define the sweep path. Define LCS Set the sweep distance and direction. Set V axis of LCS as the path

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

28 Project Node More 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

29 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

30 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

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

32 Transform Element The shell elements’ normal are adjusted when elements are mirrored.

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

36 Connection A new connection toolbar instead of spotweld toolbar. New Feature in this toolbar:  The spotweld generation speed are significantly improved.

37 Connection- create  Supports MAT100 spotwelds in solid elements, 4/8/12/16 Hexahedron elements can be created.  Support adhesive type of connections

38 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.

39 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.

42 Create Group from Set Allows 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.

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

44 Display about Node Set PreSys only shows the nodes in the set for the displayed elements/nodes/parts currently now.

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

46 Add to Part In 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.

47 VPG Module Updates - Safety Module

48 Safety Module- Pedestrian Protection 1. Click Application->Safety->Pedestrian Protection to access: 2. The pedestrian regulation support :  Pre/Processor: Marking the impact points and export the DYNA file; Euro NCAP (version 6.0, February 2012) GTR ( November 2008)  Post/Processor: Check the analysis result and calculate the scores. Euro NCAP (version 6.0, February 2012)

49 Pedestrian Protection 1. Marking the impact area 2. Load the impactor Process of operation:

50 3. Export the DYNA file. Pedestrian Protection

51 4. Submit the DYNA files in batch. Pedestrian Protection 5. Check the scores in Post.

52 Enrich the dummy library The dummy library has been enriched. The number of dummy increased from 10 to 13.

53 VPG Module Updates - Structure

54 Tire The TIRE Module allows the user to : 1.Generate tire models with user-defined characteristics; 2. Setup tire cleat test to checkout its performance; 3.Create a revolute joint between tire and suspension ; 4.Adjust tire camber/toe angle

55 The picture is popped up for users when mouse move to the parameters. Create Tire

56 Tire / Cleat Test Setup

57 Assembly the tire to suspension, and a revolute joint will be created. A revolute joint was created. Tire / Assembly

58 Adjust tire Camber/Toe angle. Camber Angle Adjust Tire / Align Tire

59 VPG Road Surface Generation Import road from built-in library (12 roads) from user’s file

60 Road / Parametrically Defined Create Parametric Road Plank RoadPothole Road Curb Road Roof Road Sine Road Crown Road

61 Road / Position The road is located according the vehicle position when loaded. If multiple road models are imported or created continuously, all the roads will be automatically connected with end to end
