NSTest is failing (the multigrid solver isn't converging for some reason,
though it appears to be spurious, as the L2 error is zero!)
Furthermore, due to a missing ASSERT, this failure is going …

I am using both Grid and MultiGrid and I am noticing that 2 render passes are made when doing a simple scroll by either clicking on the arrow caret in the scrollbar, or by calling Grid.scrollToCell({r…

The current Matlab/Octave example code ([here](https://github.com/hpcg-benchmark/hpcg/blob/master/tools/hpcg.m)) does not use a multigrid preconditioner and requires generation of the matrix by the …

While working on getting local smoothing working with `MGTransferGlobalCoarsening` (https://github.com/dealii/dealii/pull/15794), I noticed that user constrains are applied a bit inconsistently.
Th…

This is two related seg-faults/errors related to a `NonNestedHierarchy` and firedrake multigrid. I am trying to restrict a residual from one FEM mesh to a coarser, non-nested mesh, but get the seg fau…

Similar to the way we have hooks that transfer context information on subsequent solves, we need to register a trail of breadcrumbs such that we can retransfer coarse grid coefficients.
This should…

There's a start of this in `multigrid-hitting-times.R`, but it is (maybe?) having issues around convergence, possibly because the boundary of the set that's getting hit becomes jagged for the coarser …

Tracking/discussion issue for planned UI enhancements. NB: being mentioned on the list below is not a guarantee for being done at any specific time scale, nor is the order necessarily indicative of re…

This is likely an important solver for multigrid on staggered and domain wall.
