We would need an example file to look at this. We have unit tests for all template setups now which run without any issues. You might have changes something that messes with the numerics in a way that makes the OpenFOAM simulation crash (bad mesh, domain size too small, etc.). The residual output only will not tell us what might be going wrong. |

Any clue why my simulation crashes? It's nothing more then a re-run to example file #3, SimpleWindAnalyis, with some other settings and geometry, albeit also simple boxes as building inputs, a boxdomain set manually (still large, but smaller then default setting). And that's about it. Seems due to divergence in turbulence and continuity fields.
