Is it possible to specify how gradients in the solution variable are determined, e. g. by forward difference, backward difference or center difference?
For example, is is possible to write a convection term of the form U*gradC that calculates gradC using a backwards difference, so that it depends only on the value of C in cell n and n-1, and not in cell n+1?
