Adaptive Refinement of Initial Conditions #493

Open pbauman opened 7 years ago

pbauman commented 7 years ago

@roystgnr intimated to me that he was bothered we didn't have adaptive refinement of initial conditions yet. We support uniform refinement, "locally h refine" via ParsedFunction, and redistribution (again via ParsedFunction), but not adaptive refinement driven by the initial solution.

Do you have access to my "collab" svn repo? The application code there has adaptivity to initial conditions; I'm not sure if it's in good enough shape to swipe wholesale but it should at least be good enough to suggest design. This is actually a much easier problem than the transient part of the adaptivity, since you can use an exact solution based error indicator.

I don't think so.

Cool. I don't plan on doing anything about this for awhile (other priorities), but I at least wanted to capture it.
