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 .
Shape Mesh / BoxMesh Box by Region: Create box mesh in defined LCS. Define the box parameters in LCS
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.
Shape Mesh / CylinderMesh Circular Truncated Cone
Shape Mesh /Torus 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 Library Create Beam Property by Library : This function is visualized and convenient for users to create beam property.
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.

Topology Mesh Automatically average or merge all inner nodes on two boundaries if their first and last nodes have been averaged or merged. BEFORE
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
Remesh Re-space Boundary Node
Add Washer Drill Holes option allow user to drill a new hole into the mesh where has no hole. Add washer
Add Washer Select Holes option allow user select the rectangular holes to create the washer. Add washer
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
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
Drag Mesh When source element type is solid Solid faces are selected
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
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.
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 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
Align Node In old version, users are allowed to select only one line to align nodes. After updated, multiple lines are supported.
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
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
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
Create SPH Element Create SPH element on the center of selected Shell or Solid 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.
Connection • A 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
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.
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.
CAE Solvers Interface Updates • LS-DYNA 971 R6.0.0 • NEi Nastran Version 10.1 • NISA Version 18.0
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.
Rotational velocity is shown Toggle on *INITIAL_VELOCITY, PreSys will display the nodal velocity vectors for translational velocities and rotational velocities now.
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 As When Save/Save As and Exporting a model, the default folder will be the folder where the current model file comes from.
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.
