Hi CFD- family,
i created a case in Sprayfoam on my 16 core workstation. The case is running perfect using 8 cores in parallel running (decomposeParDict). When i try to run with all 16 cores, i got the following error: ".../decomposeParDict" specifies 16 processors but job was started with 8 processors. my decomposeParDict looks like: 17 18 numberOfSubdomains 16; 19 20 method hierarchicial; 21 22 simpleCoeffs 23 { 24 n ( 2 2 4 ); 25 delta 0.001; 26 } 27 28 hierarchicalCoeffs 29 { 30 n ( 2 2 4 ); 31 delta 0.001; 32 order xyz; 33 } 34 35 manualCoeffs 36 { 37 dataFile manual_dataFile; 38 } 39 40 metisCoeffs 41 { 42 } 43 44 45 // ************************************************** *********************** // Can anyone help me? Thank you very much! |

Does your decomposition results in 16 domains? If so, what does the partitioning look like?

I think you run the case with "mpirun -np 8" instead of 16...
