How to separate frontAndBack

Hello all,
I have a 2D mesh from fluent. When I run fluentMeshToFoam, it is automatically converted to a single layer 3D mesh. The front and back planes are combined in a single patch named "frontAndBackPlanes". There is a tutorial that splits the boundary patch: patch splitting for different boundary conditions However, since "front" and "back" patches share the same cell, this trick doesn't work. I know that the ultimate solution is to make a single-layer 3D mesh in fluent but is there any workaround to do it within OpenFOAM? Thanks! |

Hi!
Maybe it is a silly question, but why do you need to split it? 2D mesh -> front and back are empty, and you will need the same BCs there. Also you shouldn't evaluate anything there so I think there is no reason for that. BTW: check the topoSet and createPatch utlities. |

Or is there anyway to get a 2D face patch from Fluent directly? |

Well. Then it would be nicer to do it with blockMesh.
As I know you can't do it. So it this case I would go with topoSet+createPatch and extrude that patch. Or simply do it in fluent which is the easiest way. And as you originally asked: "is there any workaround to do it within OpenFOAM?" Yes, there is a workaround for nearly everything in OpenFOAM, but in the worst case you have to code a little. |
