Hello everyone
I meet a problem of coupling the FAM and FVM.The following is my code:

    label patchID = mesh.boundaryMesh().findPatchID("UB");
    forAll (ephis1, faceI)
    {
        
        ephis1[faceI] = ephi.boundaryField()[patchID][faceI];
    }
                    
                 faScalarMatrix CsEqn
                  (
                                        
                    fam::laplacian(Dsigw, ephis) ==(  Dsig*fac::grad(ephis1)&aMesh.faceAreaNormals())       
                   
                   );

                   CsEqn.solve();
                            
          vsm.mapToVolume(ephis, ephi.boundaryField());

But I find that it doesn't work at all during the calculation.Have I coupled the famfield ephis or ephis1 with FVMfield ephi?

regards!

Hi gschaider
Just as you mentioned in http://www.cfd-online.com/Forums/ope...uld-i-use.html

What you want is a FAM to FVM-coupling right. Something like
Code:
    
volSurfaceMapping mapper(famField.mesh());

mapper.mapToVolume(famField,  fvmField.boundaryField());
in your code copies the internal field of the famField to the appropriate patches of the fvmField (make sure the patches are of appropriate type ... fixedValue for instance)

if I I set the inputing file of electric potential ephi in 0 dir as :
----------------------------------------------
....
boundary
{
UB
{
type fixedValue;
value 0;
}
....
}
-----------------------------------------
Then I also wrote

vsm.mapToVolume(ephis, ephi.boundaryField());

in my main program for every time step.

Will the boundary condition value of ephi at UB update every time step?
