Hey Foamers!
After having troubles with the MRFZone now I face the problems with the 3D case. I made an easy geometry, open cylinder as a tank with fluid in it (now is water). I have 2 different problems but the concern for this post is about the dynamic refinement. I add to my solver the lines for updating the mesh (it's already working when the fluid is moving out of the tank) but in some cases depending on the blockmeshdict, the dynamicMeshDict and snappyHexMeshDict parameters an error appears. I saw another post with the same error but someone told that has lack of info so I'll try to explain properly my case with images. Mesh at t=0: CheckMesh.log: Code:

Anyone knows how to fix that error? Thanks, Eric |

Hello Eric,
I know your post is 2 years ago, but I got the same problem today. Did you fixed the error? best regards, Stephie |

I faced today the same problem. In my case it was because I was trying to make the sHM over a previous mesh. It worked after cleaning constant/polyMesh, running blockMesh and decomposing. Hope it will help. Regards Robert |
