Hi Everyone,
I am just runing my simulation in parallel. but I could not succeed the simualtion due to the following error message --> FOAM FATAL ERROR: Wrong number of processor divisions in geomDecomp: Number of domains : 32 Wanted decomposition : (2 2 1) From function geomDecomp::geomDecomp(const dictionary& decompositionDict) in file geomDecomp/geomDecomp.C at line 50. FOAM exiting.. I am going to use total number of 32 processors and my composerParDict is follows numberOfSubdomains 32; method simple; simpleCoeffs { n ( 2 2 1 ); delta 0.001; } hierarchicalCoeffs { n ( 1 1 1 ); delta 0.001; order xyz; } metisCoeffs { processorWeights ( 1 1 1 ); } manualCoeffs { dataFile ""; } distributed no; roots ( ); I have writen composerParDict based on DamBreak tutorial. I would be thankful to you if you have any suggestions for this error. Panneer |

Quote:
the number of domains have to be the same that are mentioned is the composition. in your example: -------- numberOfSubdomains 32; method simple; simpleCoeffs { n ( 2 2 1 ); <----- that wrong x * y * z must be 32. e.g. (4 4 2) delta 0.001; } ------- |
