GiD Pre processor (...and post??)

[blckwtr]

GiD (

http://gid.cimne.upc.es/

) is said to be your personal pre -and postprocessor, but as far as I have figured out, the only package directly downloadable is the pre processor. For the post processor to work you have to compile a package known as GiDPost (

http://gid.cimne.upc.es/support_team/gidpost.html

). Is this correct, or is this just an additional package for extra post process capabilities?

Before I buy GiD, I need to know which possibilities I have in order to solve my problems, and I have searched around for solvers. So far I have found severeal, but Elmer (

) seems to have capabilities of importing GiD files in addition to be a "user friendly" and professional program.

So my question...; is this all I need in order to solve the following:
-- linear problems
-- non-linear problems
-- CFD analysis
-- assemblies (meaning contact elements etc.)

Best regards
