5.18.5.1. *Element_Solid_Ortho Output

The following cards are needed to define the output for *ELEMENT_SOLID_ORTHO cards for the LS-DYNA application. 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.

This section covers:

 
5.18.5.1.1. Specific Options
SOLID_OPTION = ORTHO

Activates the output of *ELEMENT_SOLID_ORTHO cards.

MapStress = NO

Define if *INITIAL_STRESS_SOLID cards are written. For the *ELEMENT_SOLID_ORTHO option, set this flag equal to NO.

MapMainDir = YES

Activates the mapping of the main directions onto *ELEMENT_SOLID_ORTHO cards.

ETYP = INT

1 - Reduced integrated solid elements.

2 - Fully integrated solid elements.

This accounts for hexahedral elements as well as for tetrahedral elements. ETYP = 1 activates the mapping to reduced integrated tetrahedral elements (LS-DYNA application ETYP 10 or 13), while ETYP = 2 activates the mapping to fully (4-point) integrated tetrahedral elements (LS-DYNA application ETYP 4, 16 or 17). The number of integration points for tetrahedral elements can also be changed with NIPTETS (see option below).

NIPTETS = 1

1 - Activates mapping to 1-point tetrahedral elements(LSDYNA ETYP 10 or 13).

4 - Activates mapping to 4-point tetrahedral elements (LS-DYNA application ETYP 4, 16, or 17).

5 - Activates mapping to 5-point tetrahedral elements (LS-DYNA application ETYP 4, 16, or 17).

For the *ELEMENT_SOLID_ORTHO option, set this option equal to 1.

MapWeldline = YES

NO

Define if weldlines are considered within the mapping. You must provide the respective Moldex3D *.nwd file.

If MapWeldline = YES, define the following two cards: WeldlinePID and WeldlineRADIUS.

WeldlinePID = INTDefine the part ID that is assigned to weldline elements.
WeldlineRADIUS = DOUBLEDefine the radius for the weldline elements. This option enables adjusting the weldline radius so that the number of elements within the weldline zone can be distinguished and assigned weldline PIDs. If this option is not defined, Search_Radius and Scale_SearchRadius options are used to determine weldline zone.
