Classical FEA is a top-level organization comprised of two main finite element analysis programs (the solver and the pre/post-process) that work together. Both of these open-source programs (MYSTRAN and M3D) use a classical approach to finite element analysis. Professional structural analysts in the aerospace industry often prefer to use this method.

To learn more about the classical approach to finite element analysis, see the About page. The Tutorials page can assist with learning how to use them. If you are already familiar with Nastran, you will be able to use MYSTRAN.
