If there is no existing import format it may just be a few hours of work to add one. Usually this goes in the following steps
1) Explore the output formats of the mesh generator and see what could be useful starting point. Often there is no documentation but of course better if there is.
2) Make several minimal examples featuring different elementtypes
3) Write a parser such that it can deal with the small examples.
4) Test it with real examples
Of these 1), 2) and 4) can be done by an interested user. Time permitting doing 3) should not be too much for the development team. However, it is essential that there is a good format to work on. For Femap this is probably the case as it is intended to be a general purpose mesh generator.
