gradient of divergence
Hi all, Is it possible to represent the gradient of the divergence of a vector field in the Coefficient Form PDE other than using the Weak Form? Thanks, Tony

Definitely you can. But I think you need to somehow manipulate the form of the expression in order to do that.

Thanks Pu. We have: grad div F = [F1xx+F2yx, F1xy+F2yy]; (1) div(c*grad F) = [c11*(F1xx+F1yy)+c12*(F2xx+F2yy), c21*(F1xx+F1yy)+c22*(F2xx+F2yy)] (2) where c=[c11, c12; c21, c22], hence, it seems to me...
