Question about batch postprocessing
Hi all, I'm trying to post-process multiple files using FieldConvert and I run into the following issue (since slack channel is not very active, I posted it on mailing list): If we have multiple *.chk files and want to convert it to vtu/dat format to view in paraview, is there a way FieldConvert will process the files in bulk? I tried to write a script that does it in loop like this: for i in ../../../solvers/ADRSolver/Examples/UnAdvDiff_3DHom1D_*.chk; do ./FieldConvert-g ../../../solvers/ADRSolver/Examples/UnAdvDiff_3DHom1D.xml "${i%.chk}".vtu; done But it does not generate correct vtu files. Currently, I'm restricted to convert each chk to vtu file individually. I also read the module information of FieldConvert and was not able to figure out if there is a clever way to do this. Thanks in advance! Vidhi
Hi Vidhi, Unfortunately, there is not a clever way to convert more than one file in a single command! Try something like the following from the examples directory: for i in UnAdvDiff_3DHom1D_*.chk; do $NEKDIST/bin/FieldConvert-g UnAdvDiff_3DHom1D.xml \ $i `basename $i .chk`.vtu done where $NEKDIST is the nektar++/builds/dist directory.

But it does not generate correct vtu files. Currently, I'm restricted to convert each chk to vtu file individually. I also read the module information of FieldConvert and was not able to figure out if there is a clever way to do this.

Hi, I usually use a for look one the check file number so something like: for i in `seq 0 10`; do $NEKDIST/bin/FieldConvert-g UnAdvDiff_3DHom1D.xml UnAdvDiff_3DHom1D_$i.chk UnAdvDiff_3DHom1D_$i.vtu done Cheers, Spencer.
