Running the simulation
- Before the calculation initial and boundary conditions need to be copied from 0.org to 0 directory.
# cp -r 0.org 0
- Simulation will be running in parallel thus the parallel decomposition has to be done. The method of decomposition and the number of employed processors/cores is in system/decomposeDict.
# decomposePar > log.simulation-decomposePar 2>&1
- It is useful to run renumberMesh utility before the computation. It provides better numerical properties of matrices resulting from the finite volume method discretization of Navier-Stokes during the computation.
# mpiexec -np 6 renumberMesh -overwrite -parallel > \
log.simulation-renumberMesh 2>&1 - The number of used processors/cores behind the switch -np must correspond with the number of processors/cores in the system/decomposeDict.
- The chosen solver for this tutorial case is pimpleFoam. To launch it in parallel use the following command:
# mpiexec -np 6 pimpleFoam -parallel > log.simulation-pimpleFoam 2>&1
- See Allrun-rotating.sh script which contains the same course of steps that is described above.
