Hi Foamers,
I am new to OF, I could not find much in literature to the following question. I have a region (say regionA) already defined in topoSet (and in splitMeshRegion) as a new cellZone. Can I select only a section of a 'regionA' and under a different name so I can call it in from fvOptions as a cellZone? Can I use subset to do this or it is possible at all in OF? Thank you in advance. Dasith |

Hi Ajith,
topSet do not like defining a cellzone within already defined region. It just takes the first defined cellzone region and dump the latter. Can I name set of cells in the region with setFields? Thank you Dasith |

If I understand correctly you just want a subset of a cellSet?
So just create the cellSet two times and use the subset action on one of them? e.g. Code:
actions ( { name cellSet1; // This is the first cellSet type cellSet; action new; source boxToCell; sourceInfo { box (0 -1 -1) (0.1 1 1); } } { name cellSet2; // Same as fist one type cellSet; action new; source boxToCell; sourceInfo { box (0 -1 -1) (0.1 1 1); } } { name cellSet2; // This is a subset of cellSet2 type cellSet; action subset; source boxToCell; sourceInfo { box (0 -1 -1) (0.01 1 1); } } ); |

Hi,
Apologies for the late reply, I use alternative method for the time being and the issue is boomeranged back to me after years! The issue with subset is that , the fvOption cannot find the subSet or cellSet in the polymesh in the master region ( region A). That is because topoSet do not write on the polymesh folder unless it is defined as a cellZone. ( correct me if I am wrong ). Then why not define the region i want as a cellZone??? ![]() ![]() Any ideas are much appreciated. Thanks, Dasith |

Hi Dasith,
Try "type cellZoneSet;" instead of "type cellSet;" in topoSetDict when you define the specific part of your region that should be regarded by fvOptions. "sourceInfo" can be the cellSet you already have now and you may keep this name for the "cellZoneSet", too. This should generate the cellSet in this region mesh that you are missing now. In fvOptions you can address this part as "cellSet" again. Hope it works that way for you, too |

Hi Volker,
I just cannot figure it out, I think I am lost in old and new version topoSet terminology. my Main (big) region is 'fluidRegion' and the smaller (sub) is the 'fan' region. Fluid region is already define. Either topoSet or the splitMesh giving me erros! could you please have a look, PHP Code:
Update - 04/05/2023 Silly me, it works fine now, thank you very much guys. if anyone interested PHP Code:
