Hello all,
I have a problem in which I want to set the solution dependency of a particular subset of cells to that of another subset of cells, i.e. I need to set the fvMatrix coefficients in UEqn for a particular subset equal to a different subset, iterating per cell. I have done considerable reading about the addressing format for the lduMatrix but it isn't clear to me whether I can do what I need. Also I have looked at the setValues function in fvMatrix but that involves setting the value within the cell to a constant value. I want to preserve the dependency of the other cell on its neighbors when the equation is solved. Is this possible using the current mechanics of the fvMatrix, or would I need to create my own addressing system to allow me to do this? Any help would be great, I am kind of stuck and my thesis is dependent on getting this to work. Thanks, Austin |
