This project is part of a research effort by the T*AFSM to compare the aerodynamical forces acting on a parachute computed with remeshing. This includes remeshing with regeneration of grid points and remeshing that only involves reconnecting the current nodes. We investigated the differences between these methods in order to determine the effectiveness of the latter remeshing option.
