| Summary | 0002806: tutorial flameSpreadWaterSuppressionPanel for fireFoam crashes in parallel for different decompositons | ||||
| Description | Dependent on decomposition the simulation fails (see attached file decomposeParDict): - Option 1: Decomposing the domain to 4 processors, every processors contains parts of the three regions (region0, filmRegion, pyrolysisRegion) => Simulations without problems - Option 2: Decomposing the domain to 4 processors, not every processor contains parts ot the three regions => Simulation crashes (see log_option2.txt) => Reason probably BC filmPyrolysisRadiativeCoupledMixed in T fields in region0 and pyrolysisRegion to couple the three regions. - Option 3: Decomposing the domain to 3 processors, not every processor contains parts of the three regions => Simulation crashes (see log_option3.txt) => Different position of crash than for option 2. | ||||
| Steps To Reproduce | Problem is always reproducible. - Build tutorial with Allwmake / stop after start of fireFoam - Copy decomposeParDict in system of all the regions - Decompose all three regions / use comments to switch different options o decomposePar -region filmRegion o decomposePar -region pyrolysisRegion o decomposePar - mpirun -np 3 fireFoam -parallel resp. 4 processors (for option 1 and 2) | ||||
