Hi Foamers,

I've just wandering how can I operating my case (1 stator passage, 1 rotor passage using sliding mesh interface) with multiprocessors?

Currently I've using every method to decompospar, however, it is still cannot run with even just 2 cores!

It is running very very very slow, so who can help me out?

Thanks!

Does anybody knowing that?
Thanks!

In foam-extend this has always worked. No surprise, since I wrote the topo change in the first place.

Hi Hrvoje,

Thanks for your reply!
And it is very excite for me to get a reply from one of the OpenFOAM author!

I'm currently using the Density-Based solver: transonicMRFDyMFoam, but it is not operation with even 2 processors.
The solver is from here:
https://sourceforge.net/p/openfoam-e...ster/tree/src/

I'm not sure if it is the capability of the solver itself?

Thanks!

Could anybody know what's happens about the multiprocessing?

Thanks!

I have detailed read the introduction for the "turboFvMesh":

    Simple mixer mesh using an ggi interfaces

    This tool is used to have multiple rotating regions around the same origin
    with different rpms. Creating the cellZones is not implemented
    in this tool.
    The steps to obtain the cellZones and faceZones are:

    1) use regionCellSets utility. With this command you can have different
       cellSets for each region.

    2) run command "setsToZones -noFlipMap".  After this command the
       cellSets are transformed to cellZones.

    4) for each rotating cellZone add an entry in rpm subDict of
       constant/dynamicMeshDict

    5) in parallel you need to create from all rotating coupled-interface
       patches faceZones (if you use a ggi interface between you have already
       created these faceZones), Then you need to specify these faceZones with
       the corresponding rpm in the additional "slider" subDict in
       constant/dynamicMeshDict

However, which faceZone should I add into the "slider" subDict?
Only the two which contacted with each other, defined by overlapGgi?
And all the patches including the walls?

I'm not so sure and till I can not make it running.

Could any body help me?

Thanks in advance.
