Do you have gmsh api installed? If you do, there is another function with the same name, where you can specify labels to assign interior manifold ids explicitly, and set the interior boundary id to “-1”. There is an example in the documentation on how to do this. LucaIl giorno 14 giu 2024, alle ore
I tried to do this, but it was still wrong. I draw the interface of the
fluid-solid coupling without imposing any physical labels. It still doesn't
pass the Gridin

You should not add Physical Surface("inner wall surface", 776) of interface
in gmsh,
This interface can be determined by the step-46, this is the drawback of
dealii as I know.

Can you provide the GMSH code and a small executable that tries to achieve
what you are doing? I can take a look and figure out what is the issue :)

Hollo,
I tried your suggestion but dealii still reports an error. I don't think it
has anything to do with the grid type, it also errors when I only use
Gridin.

Loading a tet mesh works if you set-up your Mapping/FE accordingly, this is
a feature we use extensively.

Wang,
Do you have a geo file that describes the geometry? Can you remove the
"Physical Surface" lines in the geo file and regenerate the mesh.

Hello,
Thank you very much for your reply. That's what I thought at first, but I
was wrong, when I removed the corresponding physical group it was still the
same error. I think gmsh automatically sets the coupling interface to solid
when drawing the model body mesh, but I don't know how to chang
Hello,
Deal.II associates the physical group of a face with a boundary id. You
need to remove the physical group that are associated with interior faces.
