topoSetDict

hi dear foamers
I need your help I used Gambit for modeling of my case which was is a furnace I want to model flow in a furnace considering it as a porous medium with constant porosity of 0.5. I do not know how to modify the long tube-shape region as a porous media please help me if you can. some one told me I should modify topoSetDict but I do not know how to do it please help me,I am not so advanced user of openfoam. If you know please tell me in detail. thanks Mohsen |
If you look at topoSetDict, you can define sets of points/faces/cells with you different entries and sources. For the region you want, you should look at the cylinderToCell source.

I used fluent3DtoFoam and I open my "constant/polyMesh" folder I can see my boudries file but while I want to see cellZones file I just see something like these: "00/00/000/000/00/00/........" I do not what to do :( how should I modify a porous region for porousSimpleFoam solver :( |
Greetings to all!
@Mohsen: Check the file "applications/utilities/mesh/manipulation/topoSet/topoSetDict" for a complete option list: https://github.com/OpenFOAM/OpenFOAM...et/topoSetDict In addition, have a look into the tutorials that use this utility: Code:
find $FOAM_TUTORIALS -name topoSetDict On the other hand, if your converted mesh already has the cellZone assigned, then it's just a matter of using the respective name. You can see the existing cellZones by running paraFoam and then turning on the option "Include Zones". Best regards, Bruno |
hi wyldckat
thanks for your useful guidance.. i defined my porous medium in gambit as a fluid and convert it by fluent3DMeshToFoam in openfoam,but i do not know how i can define this medium in toposet or porousZones as porous media?? would you mind please help me to solve this problem... |
