NGSolve

NGSolve is a general purpose Finite Element Library on top of Netgen. With the basic library one can solve heat flow equations, Maxwell equations, and solid mechanical problems. Several add-ons are available for particular application classes. NGSolve is written in C++ and a open source. It features are elements of arbitrary order for any shape, scalar elements and vector-valued elements for H(curl) and H(div), integrators for Heat-flow, Elasticity, Navier-Stokes, and Maxwell, iterative solvers with multi grid preconditioning, and error estimators and adaptive mesh refinement.
