While working with the CalculiX adapter, you may run onto common issues. This is a collection of what we know could go wrong.

This list is definietly not complete. If after reading this, you still have issues, please ask in the preCICE forum.

## Things to check

• Are you using the same version of CalculiX and of the CalculiX adapter? The adapter installation works by replacing files of the original CalculiX, so they should be compatible.
• Can you manually run the ccx_preCICE binary?
• It should be in your $PATH • If autocompletion does not work (e.g. ccx_ + TAB key), then it is probably not in your $PATH.
• Our tutorials also require CGX (pre- and post-processor of CalculiX).
• Is CGX installed?
• Is OpenGL (required by CGX) installed?
