I'm using version 4.4.0 so it's likely something I'm doing. Petteri Peltonen, (M.Sc.)

I tried a similar test on the latest master branch and if worked fine, so it is possible that this is a bug that was recently fixed. Cheers, Douglas 2017-11-23 15:15 GMT-02:00 Peltonen Petteri <petteri.peltonen@aalto.fi<mailto:petteri.peltonen@aalto.fi>>: Hey, I would like to run a POD on a section of my 3D field on a coarser grid. For this, I would like the section to be equidistributed cartesian box and this is exactly what the '-m interppoints:box' utility does. However, I'm having trouble running the utility in parallel. When I run the command: FieldConvert -m interppoints:fromxml=base/jet.xml:fromxml=base/mesh.xml:fromfld=base/mesh_1.chk:\ box=10,10,10,-0.001,0.001,-0.001,0.001,-0.003,0.003 box1.dat the utility does exactly what I want. When I run it in parallel: mpirun -np 3 FieldConvert \ -m interppoints:fromxml=base/jet.xml:fromxml=base/mesh.xml:fromfld=base/mesh_1.chk:\ box=10,10,10,-0.001,0.001,-0.001,0.001,-0.003,0.003 box2.dat box2.dat only contains one third of the points in the box. I also tried adding box2.dat:dat:writemultiplefiles, in which case I get the correct number of points split in three different files, but the file is still somehow corrupted when I open it with paraview. What am I doing wrong? Petteri Peltonen, (M.Sc.)
