I have been able to extract the coordinates, the solution variables' datasets and now, I want to write the calculated quantity in a .fld/.chk/HDF5 file. Can this be done ? Any info will be helpful. I have looked into the Demos/Python folder of the source code but that wasn't of much help. Regards, Ishan PGR
