Hello everyone,
I have a problem with the conversion of a mesh from UNV to Foam.

I meshed my geometry with Salome and everything seems to be fine.
Then, I exported the mesh as UNV file and used to command ideasUnvToFoam to export the mesh into openFoam format.

The following error displays (see below) and the mesh is not exported.
Anyone can help with this?

I have read that the ideasUnvToFoam utility has some bug, but i couldn't figure out how to solve it.
I'd need a step by step explanation ...
Thank you in advance

Nic

Hello again,
I understood that the problem was in the patch definition in salome: it is due to the fact that i have some internal walls.

how do you define zero width internal walls in salome to mesh and export to openFoam?

Thank you
