Regarding the issue with running solverdummy

When attempting to run PreCICE’s example solverdummy on CentOS, it stops at “Setting up primary communication to coupling partner/s”. I would like to know what could be the possible issue and how to investigate the root cause of the problem

Hi @LJR,

you need to set the exchange-directory to a directory both participants can read/write to: Communication configuration | preCICE - The Coupling Library

Make sure that you see a precice-run/ directory in that exchange directory. In case this already exists at the end of the simulation, make sure to delete it before running again. It contains the connection address of each participant, which changes between runs.

Thank you very much for your assistance. The issue has been successfully resolved
