max command hangs when using scotch decomposition
 

Hi everyone,



In my solver, there is a command as follows

There is no problem, when I run in serial or parallel with simple decomposition.



But when I use scotch decomposition, the solver hangs exactly at this point.

I tried to comment out this line and then it runs smoothly.



Does anyone know why?


Thanks,
ssa.

If you want to find the max for a parallel case, try using gMax instead of max. There are loads of examples in the code, e.g. https://github.com/OpenFOAM/OpenFOAM...m/setRDeltaT.H.
