CATIA provides enough CAD/CAM/CAE solutions,I'm a aerospace graduate and have been using it for my projects, i'd also like to suggest SOLID WORKS & CREO for faster modelling solutions, if you want to do intense analysis of a model ANSYS is recommended.
NASTRAN has been around for ages. It is a general purpose FE program. Can be used for structural analysis, but it can also tackle other field problems by solving PDEs using a finite element procedure.
From what I've seen SolidWorks is common for the construction of 3d models, but it isn't great for actual FEM. For FEM work, a lot of the people I know use Ansys.
