Hi Seb, Did you try to specify the WholeExtent to be the Whole system extent and not the piece one ?
Yes I did, but it does not seem to be correct. Some wiggles appear on the contour of the first partition of the dataset. In both *.vtr files I changed the line as: <RectilinearGrid WholeExtent="0 54 0 68 0 135"> But no luck! Do you think the only way that it is gonna work is to first create *.pvtr file for each time step and then use a *.pvd file to load all the timesteps?
