Hey ho that´s the CalculiX Component for coreform cubit!
Full Model definitions for CalculiX can be done with Cubit as Preprocessor. After the run with CalculiX the results will be automatically converted for Paraview.
Here you can find the source code.
The builds can be downloaded at our website.
Or just use the links.
This component was build with Cubit 2024.8! Tested with Cubit 2024.8 on Windows 10 and Ubuntu 22.04
Also take a look at our Youtube Channel CubitCalculiX . We will post videos from examples and updates in the near future.

- Python Interface to query the result files. This can be used to run convergence studies or do mesh refinement based on the results.
- The calculix model data and the loaded frd and dat results will be saved and loaded automatically with the standard cubit fileformat .cub5
To get an overview of all new commands type
ccx ?
in cubit mode (#!cubit)
For the functions of the python interface type
ccx.help()
in python mode (#!python)
Download the build directory and point within Cubit to the Directory.
- Tools->Plugins->Add
Restart Cubit.
The Cubit Window should now show "Coreform Cubit 202x.x -- with Cubit-CalculiX 202x.x" in the Title.
Now just enable the Model Tree
- View->CalculiX Model Tree
Try to open and run the journal file "first_run.jou"
If everything works. It should compute a beam and automatically open the results with cgx and paraview.
After the run with CalculiX the results should be loaded and converted automatically. If a Job exited with errors you can try to convert it over the Button in the Job Monitor.
The mises stresses and strains will be precalculated for the S and E keys. If the preprocessing was done in cubit and the results can be linked. Then the data from the .frd and .dat can be viewed with paraview. When the linking fails, the .frd will be converted to vtu. In paraview you can see the linked and computed results with the multiblock inspector.
If integration point data was requested in the .dat, the converter computes the location of the integration points and links the results. The integration point number and the element id can be queried with paraview. The element id can be found in the cell data. The ip number in the point data.
When there are displacements in the frd file for requested blocks in the .dat. The displacements of the integration points will also be computed.
current limitations of the converter:
- totals ignored
- buckling in .dat can be queried through the python api
- contact print card ignored
- only links for complete nodal and element data
with the command "ccx result project job 'job_id' {step 'step' | totalincrement 'totalincrement'} [scale 'scale']"
The displacements from an .frd can be scaled and projected to the nodes in cubit. It has to be .frd where the mesh is ident with the one in cubit. Otherwise linking fails and no projection will be done. If a step is choosen, it will project the last available increment with displacement data. When choosing the totalincrement the related displacements will be used.
Build Process for Ubuntu 22.04 and 24.04
- After a clean installation
Update and upgrade the system, then install tools required for building:
sudo apt update && sudo apt upgrade -y sudo apt-get install cmake cmake-gui sudo apt-get install build-essential sudo apt-get install qtbase5-dev libqt5charts5-dev libqt5widgets5 sudo apt install libglu1-mesa - Install Coreform Cubit
Either download from the Coreform Website or via terminal
wget https://f002.backblazeb2.com/file/cubit-downloads/Coreform-Cubit/Releases/Linux/Coreform-Cubit-2024.8%2B52155-Lin64.deb sudo apt-get install ./Coreform-Cubit-2024.8+52155-Lin64.deb - Install Cubit-Calculix
Clone the Cubit-Calculix repository
