resdistributePar -decompose fails in postChannel tutorial
Summary
Running
mpirun 36 redistributePar -decompose -parallel
in planeChannel/results/DFSEM
crashes with
[20] Cannot find point in pts1 matching point 0 coord:(57.65 0.88207685 3.1415927) in pts0 when using tolerance 6.2398167e-06
and a following cascade of errors.
Steps to reproduce
Go to the planeChannel tutorial, and run ./Allrun to generate the cases. Then execute redistributePar
as above.
A comment
I would like to stress that getting this utility to work properly, also in conjunction with the collated file format, is absolutely critical for LES/DNS runs. Serial decomposePar
is just no longer an option, once the number of processors is in the order of thousands.
