Hello, i'm trying to import my .msh file into OpenFOAM with gmshToFoam command, but the "unhandled element 1 at line" warning appears. It is not a fatal error, but when i check the polyMesh folder, my physical surfaces are not readed at the boundary file.



Also when i run the checkMesh command, some errors appear. I write bellow the warnings that appear when i run the gmshToFoam command and the checkMesh command. Also i attached my .geo file.


The file is a NACA4412 airfoil mesh.
