upwind scheme for grad and div
 

Hi all,


I want to use upwind scheme for gradient of a volScalarField X and also for the divergence for a volVectorField Y. However, when I set grad(X) Gauss upwind, I just get the error attempt to read beyond EOF, and it is the same with div(Y).


So I want to know how to set upwind scheme for grad(volScalarField) and div(volVectorField) properly? Thanks a lot!
