CFD Online Discussion Forums - Accessing boudaryField

Hi all,

I am trying to access the boundaryField of velocity and modify that and use it for the next time step calculations. I read in the post https://www.cfd-online.com/Forums/op...read-only.html that we have to use boundaryFieldRef inorder to access it, else it throws an error saying the field is read only. I did as suggested but still the values are not reflected on the output. Are Ref fields only for reference and not for next time step or post-processing?

Below is my piece of code in the solver that converts a scalarField'Jw' into a vectorField 'U'.

Code:

 label upMem = mesh.boundaryMesh().findPatchID("upperMembrane");

forAll( U.boundaryFieldRef()[upMem], i)

{

        U.boundaryFieldRef()[upMem][i].component(vector::X) = 0;

        U.boundaryFieldRef()[upMem][i].component(vector::Y) = 0;

        U.boundaryFieldRef()[upMem][i].component(vector::Z) = Jw.boundaryFieldRef()[upMem][i];



}
