II am using CHTmultiregion in op 2.3, with scotch. There are 5 regions nested like russian dolls. I find there is insufficient cells in the innermost region for to be split by the number of processors needed for the outermost region. This situation means vast processing times.
innermost region has 2 000 cells outermost region 700 000 Can i use different numbers of processors for each region? or is there another solution?

Greetings Derek,
You can control the processor weights. Have a look into the file indicated by this command: Code:
echo $FOAM_UTILITIES/parallelProcessing/decomposePar/decomposeParDict Best regards, Bruno
