hi all
i am trying the tutorial case of multiRegionHeater and whenever i execute splitMeshRegions -cellZones -overwrite
i get the Following Error:

Create time

Create mesh for time = 0

Trying to match regions to existing cell zones.


Number of regions:5

Can you help me with this? I am new to OpenFoam and my objective after is to implement the temperature coupling to an FSI solver.....

Hi Samer.
Just today I've encountered the same error during a simulation for my thesis work...
Have you finally found a solution?
Thank you

[SamerAli]

well i worked on another strategy, but i think the solution to this problem is to change the neighbour region type in the dictionary file from fluid to region0, it will work, try it and see...

[DanAndrea87]

Ok, I'll try it...
Thank you

Hi all,

As for as now i have only solid body. My case is Incompressible, Heat transfer, Steady state.

I need to create heat flux on the surface of the solid body (@wall). And my inputs are heat flux (W/m²) for surface or (W/m³) for body.

And while running chtMultiRegionSimpleFoam solver.. I am facing this error

This is my solveSolid.H file

{

    {
        fvScalarMatrix hEqn
        (
            (
                thermo.isotropic()
                ? -fvm::laplacian(betav*thermo.alpha(), h, "laplacian(alpha,h)")
                : -fvm::laplacian(betav*tAnialpha(), h, "laplacian(alpha,h)")
            )
          ==
            fvOptions(rho, h)
        );

        hEqn.relax();

        fvOptions.constrain(hEqn);

        hEqn.solve();

        fvOptions.correct(h);
    }
}

thermo.correct();

Info<< "Min/max T:" << min(thermo.T()) << ' ' << max(thermo.T()) << endl;

How i can modify this file for my case??

Thankyou in advance
Vishsel

The error seems to come from your boundary condition. Have you a coupled boundary condition? If you have only a solid and no neighbor fluid this is maybe the problem

Hi,
I got the same problem. However, I don't know where I can find the dictionary file to change the neighbour region type from air to region0.

Please help me. I am a new person to OpenFoam.


Thanks,
TGS

Hi TGS
I have same problem now and didnt find solustion.
did you solved jet?

Hi Jialin,

Yes I solved the problem. Once I did the topoSet, I applied the splitMeshRegions -cellZonesOnly -overwrite instead of splitMeshRegions -cellZones -overwrite.

Then it showing only the available cell Zones in my case. Not showing any other regions.
