This was tested with an AMD64 processor (32 gigs RAM) on Xubuntu 18.04 LTS with OpenFOAM v18.06. The following steps use the mesh already contained in this repo and starts with exporting the unv files.
Open "rotor and stator.hdf" (found in "rotor and stator.hdf.7z") in Salome. Export stator mesh as stator.unv into prop/stator Export rotor mesh as rotor.unv into prop/rotor
start command line in prop/
follow the steps
$ cd rotor
/rotor$ ideasUnvToFoam rotor.unv
$ cd ../stator
/stator$ ideasUnvToFoam stator.unv
/stator$ cd ../
$ mergeMeshes -overwrite stator rotor
$ cd rotor
/rotor$ checkMesh
$ cd ../stator
/stator$ checkMesh
/stator$ setSet
Command>cellZoneSet rotor new setToCellZone region1
Command>quit
/stator$ topoSet
In your stator/constant/polyMesh/boundary file make sure AMI patches look like
AMI2
{
type cyclicAMI;//This needs to be changed.
neighbourPatch AMI1;//This needs to be added.
nFaces 9774;
startFace 4088405;
}
AMI1
{
type cyclicAMI;//This needs to be changed.
neighbourPatch AMI2;//This needs to be added.
nFaces 10160;
startFace 4098179;
}
/stator$ decomposePar
/stator$ mpiexec -np 2 renumberMesh -overwrite -parallel
In your parallel processor files ( e.g. processor1/constant/polyMesh/boundary) the polyMesh boundary files need to look like this for patches Side and propeller.
Side { type wall;//this will cause an error if it's not wall nFaces 21884; startFace 2003703; }
propeller { type wall;//this will cause an error if it's not wall nFaces 2308; startFace 2041234; }
/stator$ mpiexec -np 2 pimpleFoam -parallel | tee log .pimpleFoam
The simulation should now run....
