  1. New Feature in 2012 R2

  2. Preprocess

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

  5. Shape Mesh /CylinderMesh 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.

  6. Shape Mesh / CylinderMesh Circular Truncated Cone

  7. Shape Mesh /CylinderMesh Cone

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

  9. Shape Mesh / Torus User Controlled.

  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) Working Folder Solver Path Run Analysis

  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. Adjust the re-mesh regions Increased/ decreased the nodes by clicking number using the left or right mouse. 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 Select Holes option allow user select the rectangular holes to create the washer. Add 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 Create 2D elements from existing line elements; Create 3D elements from existing 1D/2D/3D elements. The element type of target element Source element type is 1D/2D

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

  22. Linear Mapping Create solid mesh by mapping the mesh from the source shell to the target shell. Select source/target elements Automatically or manually select 3 nodes respectively from source/target elements Distribute layers as requested

  23. Linear Mapping

  24. Create Arc Split Original Lines Combine Lines Split Original Lines Split the original line at the end of the created arc. 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. Assign Beam Properties Change/Add offset of Beam Element Keyword Option: wx1, wy1, wz1 Keyword Option: wx2, wy2, wz2 The keyword of beam in Ls-dyna is *ELEMENT_BEAM_OFFSET

  30. Assign Mass and SPH Property This feature can help the users to modify the Mass/SPH Element mass in bulk. Input the new Mass The average mass of selected elements

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

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

  33. Support 2nd Order Element PreSys Build 2012-12-21

  34. Support 2nd Order Element PreSys Build 2013-01-25

  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. Connection-connector Link part ID Num of layer • 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.

  40. CAD Software Support Updated

  41. CAE Solvers Interface Updates • LS-DYNA 971 R6.0.0 • NEi Nastran Version 10.1 • NISA Version 18.0

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

  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-PedestrianProtection 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 Process of operation: 1. Marking the impact area 2. Load the impactor

  50. Pedestrian Protection 3. Export the DYNA file.
