    Briefly:

     

    FEM file:

    - model file for the solver

    - ASCII (text) file that you can open in any text editor

    - includes all the solver cards

    - does NOT include geometry, only FEA entities (elems, nodes, forces...)

    - retro-compatibility with different HyperMesh versions (except newer cards)

    - as it is a text file can benefit of compressing with a good compression ratio

     

    HM file:

    - model file for usage in HyperMesh/HyperWorks

    - binary file (.hm) that can only be opened in HM/HW

    - may include FEA and GEOMETRY entities

    - newer files cannot be opened in older versions

    - usually not so compressible
