Step by step: post-processingThe solution and the mesh may be plotted by simply calling:plot (u)plot ( mesh )interactive ()The interactive() call is necessary for the plot to remain onthe screen and allows the plots to be rotated, translated andzoomedFor postprocessing in ParaView or MayaVi, store the solutionin VTK format:file = File (" poisson . pvd ")file
