I guess the first question is whether you want the convection term to be implicit in some way, usually it doesn't matter. If you don't care whether the convection term is implicit then you can discretize the convection term in anyway you like (using numpy arrays) and add the convection term as a source term. Create a function to discretize the convection term and then update a CellVariable that represents this term at every time step. Hope that helps. -- Daniel Wheeler _______________________________________________ fipy mailing list fipy@nist.gov http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
