ANSYS Fluent .msh files #77

Closed VKheyfets closed 7 years ago

VKheyfets commented 7 years ago

Hello,

Does the meshio support ANSYS Fluent .msh files? The documentation says that it does, but it looks like it only supports .gmsh files by the in the _init.py.

Thank You,

Vitaly

Wait, where does it say that ANSYS files are supported? That should be fixed, because they aren't.

VKheyfets commented 7 years ago

Well it does not say that explicitly, but the README file says that it can do *.msh file formats, which is the mesh file for ANSYS Fluent. The example also says: "meshio-convert input.msh output.vtu." I'm not familiar with Gmsh, so I am not sure if .msh is also an extension for that software.

That makes sense since the init.py file only has gmsh.

I think the .msh extension has been used for a few different things over the years, it's kind of an obvious one, especially if working under an environment mandating three-letter extensions. A third example is the one used by FreeFem++, defined in Table 5.1 ‘The structure of “mesh sample.msh”’ of the FreeFem++ manual, v. 3.48.

Where meshio's README.md lists the formats, including MSH, each is a link to a definition, MSH linking to http://geuz.org/gmsh/doc/texinfo/gmsh.html#File-formats . That's some indication which MSH is meant here.

I've proposed a more explicit listing in #78.

Thanks for PR.

Let's leave this issue open to see how much interest ANSYS meshes attract.

You got one person :-)

Yes, that would be useful. I started hacking my own converter, but haven't had time to finish it up.

Three is a party, so here you go: ANSYS mesh reading is in 1.8.0 (just released).

The only one testing so far is me, so expect rough edges. If something doesn't work as you expect, best file a bug.

Wow ... cool, thanks!

Thanks @nschloe, I appreciate it. Unfortunately it can't read my Fluent file, so I submitted #90.

If you are interested, I am happy to help, I would love to have a converter. Let's discuss on the other issue.
