Dear Saeide

that tutorial was for OpenFOAM-1.6 standard , now its not useful anymore, you can study those tutorials which contain topoSetDict such as:

Dear Mahdi,

Did you recognize other boundary condition like above that suitable for a laminar flow?

This bounfary condition work probably for both laminar and turbulent flow, I used it.

hei.. sorry for interrupt.. i also not so understand how the setSet work... can somebody help?

[da14]

Hii

Im try to simulate a porous breakwater with wave generation on waves2foam using porousWaveFoam with Gambi mesh (msh file).

My problem is that when i run fluentMeshToFoam to convert the msh file the porosity zone is not defined at cellZones. I try to use selSet newBoxToCell but my cell is not a square.

Any idea how i solve that?

Regards

Diogo Afonso

1. Instructions are given at the file "$FOAM_SRC/applications/utilities/mesh/conversion/fluentMeshToFoam/README.txt"
2. This has already been discussed at a thread dedicated to this topic, if I can find it... I think it's this one: http://www.cfd-online.com/Forums/ope...eshtofoam.html
   
3. If you Google with this search string:
   

   site:www.cfd-online.com fluent3DMeshToFoam writeSets

   you'll find a few more threads about this.

Best regards,
Bruno

Hi everyone,

I read the discussion here but I need more info on how to create cellZone using topoSet as I'm using MRFInterFoam and it seems that I have not defined cellZone.

Can anyone experienced suggest me something to go forward?

Regards
Maral

FOAM exiting

Looks like directMappedWall has been renamed to mappedWall in 2.1.0, (see official 2.1.0 release announcement)

Hey have you found anything which might help on this as I am getting a similar error from ages and I have tried several different things but this error still persists.

Please help!!

Thanks and regards,

Dear foamers,
I am performing a fluid structure interaction problem in a porous media from McT images which consists of both the solid and fluid domains. Where the solid is just an inversion of the fluid domain. I'm trying to mesh objects based on stl files by using snappyHexMesh as follows:

1. blockMesh operation
2. snappyHexMesh operation
3. SplitMeshRegions -cellZones -overwrite

Unfortunately some fragments form. I can't delete the fragments because they help ensure conformity at the interface. Otherwise I'll be having a "Master point Addressing" problem. You can find my preProcessing case file here https://yadi.sk/d/yXwpAv8_3Ry3W7
If you observe in the FLUID "boundary" file I'm supposed to just have the inlet, outlet, wall and interface conditions but there is an extra patch represents the fragments named "Out"

5
(
    Out
    {
        type            patch;
        nFaces          322;
        startFace       1101291;
    }
    inlet
    {
        type            patch;
        nFaces          8889;
        startFace       1101613;
    }
    outlet
    {
        type            wall;
        inGroups        1(wall);
        nFaces          6859;
        startFace       1110502;
    }
    wall
    {
        type            wall;
        inGroups        1(wall);
        nFaces          23046;
        startFace       1117361;
    }
    domain0_to_SOLID
    {
        type            mappedWall;
        inGroups        1(wall);
        nFaces          148834;
        startFace       1140407;
        sampleMode      nearestPatchFace;
        sampleRegion    SOLID;
        samplePatch     SOLID_to_domain0;
    }
)

And similar for the SOLID folder.

I've tried to stitch those fragments using both stitchMesh and stitchMesh -partial, but none seemed to be working.

Please can anyone help or show me another method to achieve this?

Thanks
Samuel
