Hi @quarkz  
at first sight it looks like your system is not able to find ccx\_preCICE. Before removing anything from the case:

- you shoud install calculix and preCICE adapter. See for example [here](https://precice.discourse.group/t/calculix-adapter-installation/1846/4)
- you shoud have ccx\_preCICE now and it must be in your path (e.g. somewhere in .bashrc you should point to it )
- you should run fluid and solid from two different terminals and within the directory where you find run.sh

I hope this helps  
Claudio
