ODE Integrator Interface for Aux System #726

Closed friedmud closed 10 years ago

friedmud commented 10 years ago

I keep talking about how the Aux system is for ODEs... we should actually create a layer that integrates with a real ODE integration package to allow arbitrary selection of time integration order for ODEs.

This will be useful for Hongbin for point kinetics neutronics and for RAT chemistry stuff.

Some design notes:

we will use the aux system for solving ODEs in an update form, i.e. u^{n+1} = my_ODE (single ODEs)
we will use the NonlinearSystem for ODEs in residual form (single or system of coupled ODEs)
