Data Translators

CAE Input Data

All of the CAE input data translators are bundled with the Extended Version of CalculiX for Windows.

ABAQUS and CCX INP:

This translator expands an ABAQUS input deck to remove some of the cards that are not
supported by CalculiX's solver CCX. The resultant input deck is still valid Abaqus input.

Entities translated to CCX INP:

• All syntax that CCX and Abaqus share is transferred verbatim during the
  translation except *INCLUDE. To simplify the translation process, the contents of the included files are all contained in the resultant translation.

• *BOUNDARY (expand the type formats: XSYMM, YSYMM, ZSYMM, ENCASTRE, PINNED,
  XASYMM, YASYMM and ZASYMM)

• *ELGEN

• *INCLUDE combines includes into a single file (not a requirement for CCX)

• *NFILL (bias and singular not yet implemented)

• *NGEN (cylindrical and spherical systems and parabolic generation not yet
  implemented)

• *NSET, ELSET

• *PARAMETER

• *TEMPERATURE (changes any use of the abbreviation AMP to AMPLITUDE)

This translator also translates the mesh from an ABAQUS or CCX input deck to the GMSH format.

Entities translated to GMSH MSH (ASCII 2.0/2.1):

• *ELEMENT

• *ELGEN

• *ELSET

• *INCLUDE

• *NFILL (bias and singular not yet implemented)

• *NGEN (cylindrical and spherical systems and parabolic generation not yet
  implemented)

• *NODE

• *NSET

• *NSET, ELSET

• *NSET, GENERATE

• *NSET, UNSORTED

• *PARAMETER

GMSH MSH (ASCII 1.0, 2.0 & 2.1):

This translator converts the ASCII versions 1.0, 2.0 and 2.1 GMSH mesh files to the format used by ABAQUS and CCX.

All nodes, elements and sets are translated to CCX and ABAQUS INP.

The element sets are automatically created based on the mesh partition, component name and physical name of the elements that are translated. Node sets are generated for all physical names regardless of the elements that are translated.

The element topology, point, line, surface or solid, that is translated is based on a user selection (or command line option in batch). The element topologies can be selected in the translation wizard by checking the desired box(es).

For batch mode, the command line option is:

    translate -gmsh inFile.msh (-abq|-ccx) outFile.inp elemDim
      elemDim is:
         Filter element topologies (0=point,1=line,2=surface,3=volume)
         valid values: 0|1|2|3|01|02|03|12|13|23|012|013|023|123
