Hello,
I would recommend gmsh, at least for postprocessing. The MSH file formats (ASCII and binary) are very well suited for it in my experience (small, medium model sizes) and in ascii format easy to check and modify if necessary. Plotting capabilities are as good as femap and allows for nodal and elemental results. I have created the files with text processor sometimes for small models using f06 results. I think is as good as femap .neu file and easier to read and can be used with a software that is free & open source that does not need installation and runs in all platforms (macOS, windows and linux).

I attach an example so you can check by yourselves (this is an ascii file in legacy format 2) for normal modes of a small model (remove .txt extension before opening with gmsh).
