There are some good options. Those I know are for Linux (Linux has the philosophy of open source, contrary to Windows and Mac, which look for $$$) Since you are looking free (open-freedom), I suggest to use Linux and look for the following options: OpenFOAM (oriented for CFD but with solvers for everything), Salome (pre- and pos-processing - the processing can be done with ===>) FEAP (Finite Element Analysis Program), Tochnot, and Impact (Dynamic FE Program Suit). Look also for OpenCascade, and Code-Aster (French)
As you see, there are a number of good options. If you are already a Linux user, it will be easy. If you are not and still want what you asked, get involved with open community; try for example Ubuntu Linux. If you are not, and don't want to try, then look for some pirate versions of those software listed in your question. Cheers...
