Interface Creation Problem with chtMultiRegionSimpleFoam

Hello everyone,

Im actually trying to solve a simple case of a solid heated tube (fff_solid region) with internal flow (fluid_fluid region).

My mesh is imported from Fluent.

I get the following message :

Code:

--> FOAM FATAL ERROR: 

' not type 'mappedPatchBase'

    for patch solid_fluid-zone_de_contact-trg of field T in file "/home/temisth/Documents/FlowHeatANDMultiRegion/chtMultiRegionSimpleFoam/TEM_Tube/0/fff_solid/T"

I already read https://www.cfd-online.com/Forums/openfoam-solving/216782-mappedpatchbase-error-chtmultiregionfoam.html

and related threads but can not make it works for me

Here are the following output i get from openfoam :

From SplitMesh, it seems that the fluent interface is not automatically detected :

Code:

Create time



Create mesh for time = 0

I edited manually the constant/polymesh/boundary and /constant/region/polymesh/boundary file

from

Code:

    solid_fluid-zone_de_contact-trg

    {

        type            mappedPatchBase;

        nFaces          29210;

        startFace       179561;

    }

Code:

    solid_fluid-zone_de_contact-trg

    {

        type            mappedWall;

        nFaces          29210;

        startFace       179561;

        sampleMode    nearestPatchFace;

        sampleRegion    fluid_fluid;

        samplepatch    fluid_solid-zone_de_contact-src;

    }

But it is still not working.

Code:

--> FOAM FATAL ERROR: 

Supply either a patchName or a coupleGroup for patch solid_fluid-zone_de_contact-trg in region fff_solid



    From function const Foam::word& Foam::mappedPatchBase::samplePatch() const

    in file mappedPatches/mappedPolyPatch/mappedPatchBaseI.H at line 67.

Does someone have an idea of where the error comes from ?

Thank you

I've just checked a tutorial case and the "p" in samplePatch is in upper case. OpenFoam is case sensitive so maybe the problem is there.

Code:

    solid_fluid-zone_de_contact-trg

    {

        type            mappedWall;

        nFaces          29210;

        startFace       179561;

        sampleMode    nearestPatchFace;

        sampleRegion    fluid_fluid;

        samplePatch    fluid_solid-zone_de_contact-src;

     }

It is common to miss some of these typos ;), Lets hope that could fix it!

Supply either a patchName or a coupleGroup for patch solid_fluid-zone_de_contact-trg

Thank you

Hi bro, recently I had the same question. Have you solve this problem? really thank you!
