The mapped orientations are given by the main axis of the orientation tensor corresponding to the largest eigenvalue. This enables modeling with any arbitrary orthotropic material law available in the LS-DYNA application.
| MapStress = NO |
Define whether *INITIAL_STRESS_SOLID cards should be written. For the *ELEMENT_SOLID_ORTHO option, set this flag to NO. |
| MapMainDir = YES |
Activate mapping of the main directions to *ELEMENT_SOLID_ORTHO cards. |
| NIPTETS = 1 |
1 - Activates mapping to 1-point tetrahedral elements (LS-DYNA ETYP 10 or 13). 4 - Activates mapping to 4-point tetrahedral elements (LS-DYNA ETYP 4, 16, or 17). 5 - Activates mapping to 5-point tetrahedral elements (LS-DYNA ETYP 4, 16, or 17). For the *ELEMENT_SOLID_ORTHO option, set this option to 1. |
| SOLID_OPTION = ORTHO |
Activates the output of *ELEMENT_SOLID_ORTHO cards. |
| 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. |
