Have you tried solving for "mnv" as the independent variable and making "m" simply "mnv / (n * v)" assuming you need "m" for one of the P or S variables? That might work. You could also then try doing that as a fully coupled equation. These equiation have no diffusion terms so they will be hard to solve. Depending on what you're looking for in the solution, you really need Riemann coupling and high order advection terms, which FiPy doesn't currently have. Actually, there is no explicit coupling of the equations within the derivatives unless "P" has "n" dependence so Riemann does nothing. I probably need to see how your implementing things to be more helpful. -- Daniel Wheeler _______________________________________________ fipy mailing list [email protected] http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
