This option enables the transfer of orientations stored in *.lsda format to LS-DYNA application meshes that will be used for ALE filling simulations. The option is a legacy implementation that references an outdated output format known as compositeout.
This section covers the following topics:
| SourceFile = STRING | Define the name and, if needed, the path of the source file (usually a *.dynain file). |
| TargetFile = STRING | Define the name and, if needed, the path of the target file. The target file should be an LS-DYNA application mesh. |
| MappingResult = STRING | Define the result file name. The mapping result will be written into this newly generated file. |
|
OrientationFile = HISV Nodes | To enable the transfer of orientations, define this flag. It informs the program that the orientation data is stored within the history variables (HISV). Alternatively, orientations can be derived from the element nodes. This method may yield accurate results if the mesh was well-aligned initially. |
There are some options available for source and result file formats:
|
SourceFileFormat = LS-DYNA ESI-PC Nastran HDF5 ESI−HDF5 GCODE ABAQUS STEP CSV | The source file format. The preferred format is LS-DYNA. |
| TargetFileFormat = LS−DYNA | The target file format. The only format available is LS-DYNA. |
| ResultFileFormat = LS−DYNA | The result file format. The only format available is LS-DYNA. |
| NumTargetPids = INT |
Define the number of parts in the target mesh which are considered within the mapping. This option should be followed by TargetPid#i definitions. |
| TargetPid#i = INT | Define as many part IDs as given in NumTargetPids. These parts are considered for the mapping. |
| NumSourcePIDs = INT |
Define the number of parts in the source mesh which are considered within the mapping. This option should be followed by SourcePID#i definitions. |
| SourcePID#i = INT | Define as many part IDs as given in NumSourcePIDs. These parts are considered for the mapping. |
Note: The options above specifically narrow down the scope of the mapping procedure to defined-part IDs. Other parts are ignored on both the source and target meshes.
| ALGORITHM = ClosestPoint | The only available option is ClosestPoint. Values are mapped to the nearest node, integration point, or element center. |
|
Search_Radius = SrcEleLen TarEleLen DOUBLE | Specifies the search radius for the mapping algorithm. By default, SrcEleLen is used, which sets the radius to the average element size of the source mesh. Alternatively, you can use TarEleLen to apply the average element size of the target mesh, or provide a positive DOUBLE value to define a custom radius. |
| Scale_SearchRadius = DOUBLE |
Coefficient to scale search radius. The default value is 1.0. |
| TargetThickness = DOUBLE | Define the thickness in the target shell mesh. |
| Shell_Option = COMPOSITE COMPOSITE LONG | Define optional shell output option. |
| SORT = BUCKET | Using bucket sort is strongly recommended, as it provides a substantial performance improvement for the search algorithm. |
| REPEAT = YES | Enable this option to ensure that all elements and integration points receive mapped data. When there is a significant difference in element sizes between the source and target meshes, the default bucket refinement may be insufficient to cover all points—sometimes by design. In such cases, this flag must be set to guarantee complete data coverage. |
