Mabey: meshio: [GitHub - nschloe/meshio: 🕸 input/output for many mesh formats](https://github.com/nschloe/meshio) FEconv: [GitHub - victorsndvg/FEconv: Program feconv is an utility to convert between several mesh and FE field formats, like ANSYS mesh files (.msh), MD Nastran input files (.bdf), I-Deas Universal (.unv), VTK files (.vtk), etc. If you use a Modulef format to store an intermediate mesh (.mfm). It can transform the FE type of a mesh composed of trangles or tetrahedra, to Lagrange P1 or P2, Raviart-Thomas (face) or Whitney (edge) finite elements. It also uses third-party code to perform bandwidth optimization (CutlHill-McKee optimization).](https://github.com/victorsndvg/FEconv) ---

It’s the native format of Gmsh so just open it and export from there. But be careful not to include additional wire and surface elements since Gmsh exports all 1D, 2D and 3D elements by default and physical groups have to be used to limit this to 3D elements only. ---

I have written this script to convert .msh file to .inp file which has two physical groups. import gmsh def convert\_msh\_to\_inp(msh\_file, inp\_file): # Initialize Gmsh gmsh.initialize() ``` try: # Load the Gmsh mesh gmsh.open(msh_file) # Write the Abaqus .inp file gmsh.write(inp_file) finally: # Finalize Gmsh gmsh.finalize() print(f'Conversion completed.

You need to define the physical data. gmsh works on physical groups for the export.
