ah.... So : I use file in format v3d. For a mesh that contains two blocks, they would be called called block1_timestep1.v3d, block2_timestep1.v3d, block1_timestep2.v3d, block2_timestep2.v3d, etc...
Actually, I open these v3d_files with a python tool that I have writen, translate them as vtk.vtkStructuredGrid, and write several files on the disk as TimeStep1.vtm, TimeStep2.vtm and Simulation.pvd But this takes a lot a disk space, and reading/writing takes a lot of time. So I would like to open the v3d file directly in paraview. That's why I though to use a Programmable Source in order to read all v3d files and create a "Temporal Data Set".
