So there are two parts to this - computing the meh intersections and then computing on overset meshes.
The computing part would be easy to add. Basically a mesh reader that can handle the format, and getting the interpolation stencils into the DofMap where they would act just like regular AMR constraints. As for computing the intersections, there is some fairly complicated hackery that goes on e.g. inside boundary layers where you have two or more discrete representations of the "same" surface. This has been addresses in tools like suggar++ and pegsus, so I'd want to take a look at the limitations in current tools before biting off this part of the process. What are your thoughts? -Ben On Jul 3,2013, at 11:33 AM, "Molina Bhatia" <[email protected] > wrote: > Hi, > > I am curious if there has been any interest/discussion towards an > overset grid system for solution of a system. libMesh does seem to have > some functionality of doing solution interpolations/transfers between > meshes, but I am wondering how much of this would be directly applicable > for solution on overset grids. > > From the little that I know about the overset system, there seems to be > a need to identify holes in background meshes where other blocks of meshes > are to be embedded.
