Hi:
Sorry I just have to respond. Usually I'm a big defender of PTC I still believe Pro Engineer is the best CAD package to be had. However when it comes to FEA work
just the concept of a lite package should give concern. I like Mechanica, but it is no Nastran/Patran or Ansys and it has limitations. A lite Mechanica, its bad enough that
people don't understand the limitations of a full version of Mechanica. Yes these things give results, but unlike CAD modeling seeing should not necessarily be believing in FEA. So depending on your application I would choose something more robust where you have real confidence in the results based on the limitations of the underlying mathematics.
