oook, none of those programs are substitutes
🙄
ProE and
Solidworks are 3d engineering modeling software that are able to analyze loads and all sorts of fun stuff as well.......and you gave me links for a mapping (2d) cad programs. may as well given me google sketchup lol. Not to mention in the industry, those two programs are pretty much the industry standard which is important
as for
fluent, you apparently have NO idea what it is do you? it is a (CFD) fluid dynamics flow analysis program that deals with stuff like drag, lift and all sorts of goodies that are dependent on your model and mesh. why you gave me a CG link is beyond me
once again, osx is not ideal in many cases PERIOD
the fact that osx does not have a viable option for mathcad is a downer as well
