Dear Foamers
I want to define an interior plane inside my domain for my inlet boundary condition (for using mappedVelocityFlux B.C. we need an interior patch). I searched the whole forums and found that there is no such a concept in OpenFOAM. one way is to create a cyclic baffle (createBaffles). I've also studied all the posts regarding createBaffles and also all the tutorials in openFoam: Code:
find $FOAM_TUTORIALS -name Allrun | xargs grep -sl createBaffles Code:
/opt/openfoam211/tutorials/heatTransfer/buoyantSimpleFoam/circuitBoardCooling/Allrun /opt/openfoam211/tutorials/incompressible/pimpleFoam/TJunctionFan/Allrun /opt/openfoam211/tutorials/lagrangian/porousExplicitSourceReactingParcelFoam/filter/Allrun /opt/openfoam211/tutorials/multiphase/interFoam/ras/damBreakPorousBaffle/Allrun Code:
createBaffles [OPTIONS] <faceZone> <(masterPatch slavePatch)> But I generated my mesh in Gambit so I can not define the required boxes that are needed by topoSetDict. I defined an interior plane in Gambit. then export it to OpenFOAM using fluent3DMeshToFoam. the interior plane converted to faceZone automatically. so I have a faceZone that is needed for createBaffles. I also need 2 cyclic patches too. I added them manually into my boundary Code:
type cyclic; nFaces 0; startFace ???; is there any simpler method for creating a cyclic baffle using Gambit? can this cyclic baffle be created in Gambit and then be exported to OpenFOAM? Any help will be appreciated.

I've found that if we manually add two cyclic patches with nFaces=0 into the boundary of polyMesh just like in TJunctionFan:(a cyclic baffle for fan b.c.)
Code:
fan_half0 { type cyclic; nFaces 0; startFace 10125; matchTolerance 0.0001; neighbourPatch fan_half1; } fan_half1 { type cyclic; nFaces 0; startFace 10125; matchTolerance 0.0001; neighbourPatch fan_half0; } I meshed my Geometry in Gambit so I don't have a blockMeshDict. If I only add the above lines into my boundary without blockMesh , The CheckMesh Gives Error ![]() ![]() What can I do??

i am faceing a similar problem at the moment! Did u find a solution to this? Or to other users, can u give a hint. I imported an external mesh and want to create baffles from faces. How can one do that? thx!! |
