A system defines a set of unknowns which in general are tightly coupled. This is especially the case for a LinearSystem, where the expectation is there is an underlying matrix object which will hold the discrete operator coupling all the variables in that system. The general approach for adding other post-processing fields is by adding another system. Usually the "System" class is sufficient - it will give you a solution vector and DOF storage, which is all you need to do to have explicit post processing variables. Then your existing output code will write the variables in all systems in your EquationSystems object. -Ben ------------------------------------------------------------------------------ Ridiculously easy VDI.
