A possible situation, without an error: one or both/multiple participants display the message Setting up master communication to coupling partner/s and nothing happens, even though this step should complete instantaneously.

This is a standard issue that many users face. You start both solver of your coupled simulation and they both hang at: (0) 18:57:09 [impl::SolverInterfaceImpl]:253 in initialize: Setting up master communication to coupling partner/s What could be the problem? Let’s take one step back and have a lo…
