How do I get an .inp file from Gmsh? I need to create a simple geometry and mesh it and define the boundary conditions in Gmsh and export it as an .inp file at the end (because I need to use it in a third party solver). I couldn't find much help from the documentation of Gmsh it seems there exists a mesh file format in Gmsh that exits in two flavors: ASCII and binary.

Any suggestion would be appreciated.

    $\begingroup$ .inp is a pretty generic extension. Is there any formal format specification or where is it going to be used? $\endgroup$ – Anton Menshov Mar 17 at 19:09
  • $\begingroup$ @AntonMenshov, I have a solver that gets .inp files created in Abaqus, but I don't have access to Abaqus, so I found out that it is possible to create inp files using gmsh, but I had a look at the documentation of gmsh and I couldn't figure out how to create an .inp file with gmsh. that's the story. $\endgroup$ – Dude Mar 18 at 13:34

As you want to get any suggestion, here are mine:

If you need to get started with gmsh from scratch, take a look at their tutorial section here, their wiki or on youtube.

You can mesh your created geometry and export it as an .inp file. In the gui use: File -> Export -> then select .inp as file format. If you want to use gmsh from the command line look here. For defining boudary conditions take a look here. I'm not 100% sure but I don't think you can define boundary conditions as such in gmsh. You'll have to create a Physical Group for that, see her in their documentation.
