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...

indeed! unfortunately i just forgot to change it in my runscript. thank you very very much!
