potentialFoam giving strange error when initialising simpleFoam
3 Attachment(s)
Dear OpenFOAM users,
I want to run a 3D simulation of a double element wing with endplates. The mesh is around 5 million cells. However when I run simpleFoam it will immediately diverge. Therefore I want to initialize the simpleFoam run by first running potentialFoam. However, I keep getting a very strange error which does not give me any information: Code:
Calculating potential flow I hope someone has had this error before and knows what to do. By the way, I am running OpenFoam 2.1.1. |
Greetings maero21,
"sigFpe" means this: http://en.wikipedia.org/wiki/SIGFPE#SIGFPE Quote:
This usually has to do with bad boundary conditions or a damaged mesh. You can use checkMesh to ascertain the quality of the mesh: Code:
checkMesh -allTopology -allGeometry Bruno |
Thank you! Indeed the mesh failed 1 mesh check. It says that it has found "cells with small determinant". I am guessing that is the reason it divides something by 0 in the solving.
How can I see those small determinant cells? I have generated the mesh in Pointwise, but apparently Pointwise is not good with 3D meshes? That would be strange, right? |
Quick answer:
Code:
foamToVTK -cellSet nameOfCellSetIndicatedByCheckMesh |
