I was wondering whether there is a suggested strategy to implement something like a timestep splitting method for systems of PDE's (NS) in Petsc. By timestep splitting I mean this: advance independently in time each term of the equations, then add all the solutions to get the total effects. >From my basic understanding of the TS object, I could basically define only one RHS function. Is creating several TS objects a recommended approach? What are the downsides of this?
Many Thanks, --g
