I am trying to solve a fluid flow problem over a range of inlet flows using a parametric sweep. The solution does not converge at higher flows, so what I would like to do is run the sweep until it fails to converge, then perform an adaptive mesh refinement, and continue iteratively repeating the sweep and mesh refinement until the sweep succeeds. I have not found a way to do this, so any help would be appreciated.
An alternative approach I tried to set up was to run an adaptive mesh refinement following each step of the parametric sweep, but no matter how I set it up, it always runs the parametric sweep inside the adaptive mesh refinement (thus always failing).
Anyone succeed in doing this, or can anyone suggest an alternative approach? I don't know exactly what part of the geometry is causing the problem, so I can't use a locally fine mesh. I tried a very fine mesh over my entire geometry which got me further along the sweep, but took 9 days to solve.
