| ALGORITHM = ClosestPoint
ElementSizeSearchRadius |
The ClosestPoint option is the most commonly used feature. It accounts for most of the mapping purposes being targeted with the Envyo application. Beginning from the target mesh, the next element or integration point is identified and its data is transferred onto the target mesh. The ElementSizeSearchRadius option has been implemented in order to map results from mesoscale process simulations using shell elements onto the target mesh. Therefore, the target mesh element size is used as a search radius, whereas the source mesh elements is projected onto the target mesh along the source meshes normal, and a check is performed to see if the intersection is within the target element. The element size can be scaled using Scale_SearchRadius - see below. |
|
Search_Radius = SrcEleLen TarEleLen DOUBLE | Search radius declaration for mapping algorithm. SrcEleLen is default, which uses average source mesh element size as the search radius. Average target mesh element size can be used by defining either TarEleLen or a positive DOUBLE value. |
| Scale_SearchRadius = DOUBLE |
Coefficient to scale search radius. The default value is 1.0. |
|
MapStress = YES NO | Define if stresses have to be transferred or not. |
|
MapStrain = YES NO | Define if strains have to be transferred or not. |
| NumFibers = INT | For *MAT 249 UDFIBER, this value must be equal to one. |
| FiberID#i = INT | Define as many fiber IDs as given in NumFibers. For *MAT 249 UDFIBER, this is only one integer. |
| ETYP = INT |
1 - Reduced integrated solid elements. 2 - Fully integrated solid elements. |
|
SourceMaterialModel = 34 234 235 249 2491 | Define the material ID corresponding to the numbering in the LS-DYNA material manual. For the mapping of fiber orientations from *MAT 249 UDFIBER, the value is 2491. |
| SOLID_OPTION = ORTHO | Tells the Envyo application to generate *ELEMENT SOLID ORTHO elements from the mapped orientations. |
| TargetOption = OpenFOAM | With this option, the Envyo application handles the data properly to link LS-DYNA mesh to OpenFOAM. INN=2 must be declared to use this option. |
| INN = INT | This flag is similar to the invariant node numbering flag in LS-DYNA provided in the *CONTROL_ACCURACY card, see [19]. To properly calculate orientations with respect to the element coordinate system, the program needs information about how the LS-DYNA application calculates the element coordinate system. The default is similar to the default in the LS-DYNA application: Off. TargetOption=OpenFOAM must be declared to use this option. |
|
ConsiderStacks = YES NO | Define if stacking sequence must be considered. |
| 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. |
|
HISV_HANDLING = YES NO CLEAR | Enables you to move and modify history variables in a user-defined way. Regarding the meaning of histories, refer to [20], [4]. If CLEAR, all history variables are removed before generating the result file. If YES, define as many history variables as must be modified (see Equation Parser). |
| MAX_NUM_HISV = INT | Define a new maximum number of history variables. This is an easy way to get rid of unwanted histories that are not useful to the new model, but also enables extending the amount of histories being output. If a history variable is being moved to a position which is higher then the actual number of history variables in the input deck, the number of histories are extended automatically. |
