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

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/html/index.html
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
