Discovered in the context of precice/precice#1914 (comment) Copying here:
{fluid-openfoam:1, solid-nutils:1} fails consistently with some network error if I first start Nutils and then OpenFOAM.

- I consistently reproduce this on my system: starting with Nutils breaks, starting with OpenFOAM works
- I cannot replicate this issue with OpenFOAM-CalculiX of the same tutorial
- I cannot replicate this issue with OpenFOAM-Nutils in the channel-transport
- I cannot replicate this issue with the Python solverdummies.
- I do get the same error if I try to (indeed) interrupt Nutils during initialization. But why does this always happen for me in the perpendicular-flap?
- @IshaanDesai reproduced this.
