Hi, I have several checkpoints and in each one of them, I have info.xml and couple of fld files, since I run in parallel. I create my vtu files along this line: for j in {0000000..0000003}; do for i in {0..12}; do FieldConvert ../Cyl.xml Cyl_$i.chk/P$j.fld Cyl_$i.chk/P$j.vtu; done done The problem is to create a movie of unsteady results, I need to have all the file in one place. I also tried this: for i in {0..12}; do FieldConvert ../Cyl.xml Cyl_$i.chk/Info.xml Cyl_$i.vtu; done but the output has only the mesh result and not pressure, velocity and etc. Can you please tell what is the easiest way to post-process multiple fld file to make a movie easily? ----------------------------------------------------------- Shervin Sammak Research Assistant Professor Center for Research Computing University of Pittsburgh 4420 Bayard St Pittsburgh, PA 15213 E-mail: shervin.sammak@pitt.edu ~ You chase quality and quantity will chase you.
