Hello

I'm using ANSYS mesher to export .msh file for OpenFOAM. I'm having some issues on my mesh because even if i select all of my boundaries and give them named selections, when using fluent3DMeshToFoam i'm getting a number of new boundaries.

My mesh uses 5 different volumes (the main enclosure and 4 porous media volumes) that are all under the same component with the "Share" topology. When the named selections contain surfaces from different volumes though, it divides them in different boundaries.

This issues I'm having came after I modified an existing project, moving one of the 4 porous media and modifying the main enclosure to follow the movement of the other volume. Before, the same model was giving the expected results, having boundaries only on my named selections.

Anyone had the same issue before? I would like to solve this without having to make the whole model again.

Thanks in advance

Alessandro
