Running Simulation - Parallel Run - Domain Decomposition
To run simulation in parallel the model regions have to be decomposed first. Utility decomposePar reads settings from system/decomposeParDict, it is recommended to use automatic decomposition method scotch.
numberOfSubdomains 4; method scotch;
Each region has to be decomposed individually:
# decomposePar -region spiral > log.decomposePar.spiral
# decomposePar -region rotor > log.decomposePar.rotor
# decomposePar -region drafttube > log.decomposePar.drafttube
Bash script can be used for decomposition:
#!/bin/sh decomposePar -force -region spiral > log.decomposePar.spiral & decomposePar -force -region rotor > log.decomposePar.rotor & decomposePar -force -region drafttube > log.decomposePar.drafttube
