The finite element method (FEM) is a numerical method for solving problems of engineering and mathematical physics. Typical problem areas of interest include structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential.

Hercules is an octree-based finite element earthquake simulator originally developed by the Quake Group at Carnegie Mellon. Hercules is used to solve large-scale earthquake wave propagation problems. For instructions on how to build, install and execute Hercules, please read the documentation below.
