description             NGSolve Finite Element Library
long_description        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.
