YAFEMS
Yet Another Finite Element Method Solver
YAFEMS (Yet Another Finite Element Method Solver) is a FEM solver for Linux and WIndows that reads a MED mesh file produced by Salome (http://www.salome-platform.org/) with certain groups created into the mesh, and with the help of an input text file (.yaf), performs a 3D or 2D plane stress or plane strain analysis and creates results in plain text format and in MED format. This way a complete analysis can be carried inside Salome, where a mesh file can be created, exported and read by YAFEMS with the help of a .yaf input file and post-processed within Salome using ParaView. New in v0.4 - More performance boost due to the implementation of the Cuthill-McKee algorithm. -
