description         Elmer is a tool that can solve a large number of partial differential equations
long_description    {*}${description} making it an ideal tool for multiphysical problems. \
                    It includes models for structural mechanics, fluid dynamics, heat transfer, \
                    electromagnetics and beyond. Elmer can also be used on massively parallel HPC platforms.
