Program to export a "Modal Neutral File"
Program to export a "Modal Neutral File"
(OP)
Hi everybody,
I have to upgrade an Adams View Simulation to include a flexible object instead of a rigid one. Adams-Flex requires a "Modal Neutral File" MNF, that is exported from a finite element package (Nastran, Ansys , Abaqus etc. ). However I don't have access to any of these at the moment.
I have CatiaV5 but I don't believe its possible with this program, otherwise I wonder if there is any freeware readily available to do it?
Any ideas would be appreciated.
Kind regards
Philip

There's no particular reason why you need a high end package to create them, just get the file spec from MSC and then write a translator in fortran (trust me).

but i don't think catia exports their model file ... maybe you can get it to print out a text version, which you can reasonably quickly edit/reformat with word (or fortran). i thought catia's analysis was pretty much internal.
