If you've got the same number of "auxilliary" variables as you do conserved variables, then just adding another vector is the most efficient way to go. If you expect to want to cache more intermediate calculations (e.g. Mach number, stabilization terms, nodal source/convection terms) eventually and there's no one-to-one correspondance with conserved solution variables, then you might want to just create an extra ExplicitSystem and use its solution vector. --- Roy ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
