different between serial and parallel running in reading pointzone
 
Dear foamer
I have problem with parallel simulation of new cases.

I have a pointZone as movingPointsZone that read by this code in a solver
Quote:
const pointZone& pz = fvMesh_.pointZones()[movingPointsZone_];
Info <<pz<<endl;
when I run serial, the output is same as pointZone in polyMesh/pointZone.
when I decompose mesh and run parallel, the output is very deference.

for example
in serial

in parallel

if I change decompose method

in parallel running, the ids is all deference from pointZone, why?
Thanks
