How to convert a mesh into openfoam format
I have a following triangular meshes for a 3d geometry ( stl format).
so far I am using gmsh, I am trying to figure out:
How to convert above mesh ( .stl and .msh formats) into openfoam format:
If I use: gmshToFoam new.msh
--> FOAM FATAL IO ERROR:
No cells read from file "new.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: new.msh at line 4995.
From function readCells(..)
in file gmshToFoam.C at line 721.
How to fix above error.
is there any interactive or alternative software that I can use to convert a mesh into foam format i.e. into blockMeshDict.
I think the problem you're having is due to a simple reason: you have a 3D surface mesh, not a 3D volume mesh.
This is why you're unable to convert the mesh directly to OpenFOAM, because OpenFOAM works with 3D volume meshes.
You either finish generating the mesh:
