Hi,

I want to change my boundary conditions during runtime. For the Dirichlet conditions I have found a way to set up the conditions in the code:

I have choosen fixedValue for the boundary type and I updated it in the code using:
U.boundaryField()[patchI]== mynewScalarField;

I have tried the same with fixedGradient type for a Neumann Condition but it doesn't update the gradient value. (I have reviewed it with .snGrad()).

Maybe someone can give me a useful hint,
thanks, m.
