Mesh export with mid side nodes
I am trying to export a mesh in .msh format and read it in my own code.
My code uses properties of quadratic tet elements. When I try to export the mesh using mid side nodes, I still get the linear elements in output mesh file. Is there any way I can export mesh with all the mid side nodes ?

The fluent msh format is a linear mesh format. If you want quadratic mesh, you should export in a FEA format such as ANSYS or Nastran. These formats support quadratic mesh.

Thanks. But I don't know how to do that. All the options I see for exporting are,

Do you have access to ICEM CFD? If so, choose that format. THen load the mesh in ICEM CFD and you can export to about 100 other formats.

It may be that the FEA options in ANSYS Meshing are hidden some how by your physics setting or something like that... Not sure.

Okay, Thanks. I used FE Modeler in workbench to save it in Ansys mesh format.
Now I can see all the nodes in the mesh file.
