You can also represent the system in an entirely uncoupled manner. That would reduce the size of memory and provide an alternative result. If the time step is small enough the uncoupled and coupled formulations should be the same. > What do you mean by know the answer? I just meant some analytical result or behavior such as bounded values or conserved quantities.

That helps. Could you hold some of the variables fixed (by changing coefficient values or time steps for some equations) and then evolve only one or two of the equations for example. -- Daniel Wheeler _______________________________________________ fipy mailing list [email protected] http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
