NASA has made nastran open source on GitHub. Look for nasa/nastran there. The download includes all source files and pdf files of the nastran documentation. The exe file was created on an ULTRIX machine so if you have one of those you should be up and running. The rest of us will have to figure out how to compile and link the program and create a suitable run script.
The build is not for the faint of heart. At this point I have built using Visual Studio Fortran under Windows XP and gfortran using minGW on a Window 8.1 machine. Don't expect a competitor to the commercial nastran codes. But for those of you with fortran and nastran experience you can add a sparse solvers such as UMFPACK and ARPACK.
