changing the boundary conditions values
 

Hi,
I have for example the following code.
BoundaryField{

inlet {
type fixedValue;
value uniform 10;
}
..
....


}

I want to change the value 10.

can someone tell me which method I have to use? I looked in fixedValueFvPatchField.C
but value can t be set there.

best regards.

Hello!
 

Dear gerado,

I think you can change the specified value for each cell of your boundary just with:

label boundaryID = mesh.boundaryMesh().findPatchID("boundaryName");
const fvPatch & boundaryPatchName=mesh.boundary()[boundaryID];

forAll (boundaryPatchName, faceI)
{yourVariable.boundaryField()[boundaryID][faceI] = appropriate Value for this face ;}

Goodbye!

Dear Gerado,

label boundaryID = mesh.boundaryMesh().findPatchID("boundaryName");
yourVariable.boundaryField()[boundaryID] == 20;

That's it.
