| Summary | 0003677: PatchFlowRateInjection Hangs in parallel execution | ||||
| Description | The PatchFlowRateInjection hangs as was reported and fixed in https://bugs.openfoam.org/view.php?id=2111. According to user Tniemi: In function parcelsToInject at PatchFlowRateInjection.C, the code calculates a random number to check if an additional parcel should be injected. However, each processor can create a different random number and thus some processors may think that a parcel should be injected while others do not. This creates a hang up in the injection loop in setPositionAndCell. The solution would be to calculate a global probability for additional injection in parcelsToInject function. | ||||
| Additional Information | Solution for the problem is givein in https://bugs.openfoam.org/view.php?id=2111. Lines 165 PatchFlowRateInjection.C in random a number for each processor individually, The patch is if (Pstream::master()) { injectProb = this->owner().rndGen().position(scalar(0), scalar(1)); } Pstream::scatter(injectProb); | ||||

> Solution for the problem is give in in https://bugs.openfoam.org/view.php?id=2111. Correct, this is already solved. |
