I am trying to run a turbulent flow in a pipe, but I am getting some problems to run the mesh conversion using the command ideasUnvToFoam
I runned this command: ~$ ideasUnvToFoam innerFlow.unv The conversion terminated with this following error: Adding cell and face zones Face Zone obstacle 3882 ideasUnvToFoam: ideasUnvToFoam.C:1287: int main(int, char**): Assertion `nouveau > -1' failed. Aborted I already tryed to remesh many times with the same refinement, coarser refinement and finer refinement, but I always get the same error. I tryed different versions and different distributions of OpenFOAM, always terminating with the same error. How to find out the cause of this error? |

Well you can look at the source code here:
https://github.com/OpenFOAM/OpenFOAM...ToFoam.C#L1287 And we can see it's in a for loop that variable "nouveau" is declared with the value of -1. For face zones labels, the values should be positive, so the fact that you're seeing -1 it means the label has not been set, so your face zone "obstacle" is not being loaded correctly. I don't know much about the file format - but to me it looks like your mesh might have some issues. Do you need the faceZones to be constructed at this stage or could you leave them out of the ideas unv format and produce them at the OpenFOAM level once you have your polyMesh? You could define your "obstacle" afterwards using the topoSet command |
