Hi Giuseppe, Thanks for sending those output files, I could visualize the results on non-moving mesh using Paraview 4.1.0.
Unfortunately, I have mesh-that is deformed at ever time step, so need to update the mesh in the Paraview. I hope Paraview incorporates this feature soon, just like it can do for file saved in VTK format. Thanks for your help, I will keep looking.
