Med Reader Plugin for ParaView
Using Code Aster the most suitable format for writing postprocessing data is the Med format. One may use then Gmsh or Salome to visualize the results. Both are pretty nice tools only Gmsh is somewhat limited in its postprocessing capabilities and Salome brings a huge overhead. Especially when considering that the postprocessing module of Salome (ParaVis) is a revamped version of ParaView. So why not use ParaView instead?
