dump / exo exodusii / file_name/ mo_name [ psets ] / [ eltsets] / [ facesets file1 file2 … filen ]

Write a mesh object to a file in the Exodus II format. The keyword pests as token 5 will cause all psets (lists of vertex numbers) associated with the mesh object to be written to the ExodusII output file. The keyword eltsets as token 6 will cause all eltsets (lists of cell numbers) associated with the mesh object to be written to the ExodusII output file. If face set information is being provided from files (file1 file2 … filen) the format of the file is written in AVS UCD cell attribute format. The first column is the global cell number, the second column is the local face number.

SYNTAX:

Dump plain ExodusII file with no vertex set, element set or face set information:

dump / exo / file_name/ mo_name

dump / exodusii / file_name/ mo_name

dump / exodusII / file_name/ mo_name

Dump ExodusII with vertex set, element set, and face set information. Note facesets will be created for all the nodes in each pset, and for all elements in each eltset. This can generate a large number of facesets.

dump / exo / file_name/ mo_name / psets / eltsets / facesets

Dump ExodusII file with vertex set, element set and face set information where face set information is read from files. This avoids automatic facesets generated for all psets and eltsets. Only the facesets in the files listed in the command will be used to define facesets:

dump / exo / file_name/ mo_name / psets / eltsets / facesets file1 file2 … filen

Dump ExodusII file with vertex set, element set and no face set information:

dump / exo / file_name/ mo_name / psets / eltsets

Dump ExodusII file with no vertex set, no element set and face set information from files:

dump / exo / file_name/ mo_name / / / facesets file1 file2 … filen

EXAMPLE WITH FACESET FILES:

The following are examples for writing an ExodusII file with top and bottom facesets for a hex mesh.

If face set information is being provided from files (file1 file2 … filen) the format of the file is written in AVS UCD cell attribute format.

The first column is the global cell number, the second column is the local face number.

Output ExodusII file using facesets:

The ExodusII file is written as a binary file and can be read by various visualization software such as GMV and Paraview. For documentation on the ExodusII API visit <http://gsjaardema.github.io/seacas/md/index.md

The mesh written to the ExodusII binary file with the following mesh object information. (The Exodus utility ncdump is used to convert the binary to ASCII file shown here).

Number of nodes and elements are num_nodes and num_elem

The mesh materials in itetclr are written as blocks so num_el_blk are the number of itetclr materials.

The face sets are written as side sets, so num_side_sets are the number of facesets.

The elements for the facesets are in elem_ss1

The corresponding faces of the elements are in side_ss1
