Using the mesh generated through gmsh in OpenFOAM
I am trying to convert the mesh generated through gmesh to Foam.But I am getting the following error:
--> FOAM FATAL IO ERROR:
No cells read from file "cyl.msh"
Does your file specify any 3D elements (hex=5, prism=6, pyramid=7, tet=4)?
Perhaps you have not exported the 3D elements?
file: cyl.msh at line 30956.
From function readCells(..)
in file gmshToFoam.C at line 721.
The error seems to be pretty clear, what kind of mesh are you trying to convert? Did you define the physicals properly in your .geo?
I have the same problem. I managed to create physical surfaces and the physical volume and they even show up in gmsh. But how can you make your internal 3D cells physical?
Additional question: How can I display my internal mesh in gmsh?
p.s.: I think gmsh is an app which can produce beautiful products but it is very hard to understand how you actually do thing.
