| Summary | 0001043: Result of forces-Object on parallel slaves | ||||
| Description | I have an application, where I need the value of the forces and moments on a selected patch on all processors in a parallel run. I used a single call to forcesObject.calcForcesMoments() for this purpose. This worked in OF2.1.x. In OF2.2.x, some binning was introduced and the parallel treatment changed from a single call to "reduce" to a "listCombineGather". Thus the result is only valid on the master processor. | ||||
| Additional Information | I corrected the behaviour by adding calls to "listCombineScatter". Thus the result is distributed to all slaves. In src/postProcessing/functionObjects/forces/forces/forces.C : @@ -843,6 +843,8 @@ void Foam::forces::calcForcesMoment() Pstream::listCombineGather(force_, plusEqOp<vectorField>()); Pstream::listCombineGather(moment_, plusEqOp<vectorField>()); + Pstream::listCombineScatter(force_); + Pstream::listCombineScatter(moment_); } | ||||
