Some scripts that is usable when running CalculiX and salome

intended work flow

• Mesh in salome. I have only tried the Netgen-1-2-3 mesher...

• Export the mesh as unv.

• Convert to inp-file

    unv2ccx Mesh.unv
  

• Strip of all non 3d meshes (if preferred)

    only3d Mesh.inp mesh3d.inp
  

• If surfaces is needed, for contact or CFD

    surfSet Mesh.inp
  

• make jobfile.inp

• run simulation

• extract the nodes, nodesets and results into csv-files

    nodExtract mesh3d.inp
    resultExtract jobfile.frd
  

Now you easily can import into python (or other) for easy processing and plotting

unv2ccx

A fantastic tool written by Ihor Mirzov. Thanks Ihor!

Note! unv2ccx is a GPL-v3 licensed code. The source code can be found at:

https://github.com/imirzov/unv2ccx.git

unv2ccx converts unv-files to inp-files for calculix.

only3d

Removes 1D and 2D elements from the input file. Netgen uses these when constructing the solid mesh.

resultExtract

Extracts the results in the frd-file to csv-files. Convenient when post-processing in python.

nodExtract

Writes the node info and nodsets to csv-files

surfSet

Creates a file with the surfaces defind. The element sets from salome are used. Only TET-mesh is accepted.

surfSet filename.inp

gives a file filenameS.inp

install.sh

A simple installer. Just copies the files to ~/bin and maes them executable. Run from this directory.
