Hi everyone. I’m using FEniCSx in combination with Bempp to solve a problem that couples FEM and BEM. I would like to know if it’s possible to run both parts in parallel using MPI, and if so, how to manage the communication or compatibility between the two frameworks. I tried to run the fenicsx example and I get an error.

We’ve had a similar question to this over on the FEniCS discourse ([About the mesh and data Synchronization for FEM–BEM Coupling - General - FEniCS Project](https://fenicsproject.discourse.group/t/about-the-mesh-and-data-synchronization-for-fem-bem-coupling/17655)). I’m going to send a detailed reply there that should also answer this question. Feel free to post further questions either here or there if you have any
