Hello,
Can FiPy solve an equation containing a convection term but no diffusion term (ie diffusion coefficient = 0)? It would seem this would cause a problem with calculation of the Peclet number. The workaround I was going to use would be to 1) implement the convection term as a source term or 2) choose a very small diffusion coefficient so that the equation could be implemented using the built in convection schemes. Thanks, Chris Calebrese
