In the end, all I really want is get access to the underlying is->data->idx
without having to worry about the subclass of is.

ISBlockGetIndices returns the indices
The reason the code works this way is that normally
-ksp_error_if_not_converged is propagated into the inner (and innerer) solves
and normally it is desirable that these inner solves do not error simply
because they reach the maximum number of iterations since for nested iterative
methods

Good question. I can see not worrying too much about convergence on the
coarse grids, but to not allow it ... and now that I think about it, it
seems
Hello,
I’m trying to get multilevel solvers to error out when coarse levels are not
converging, but I’m failing…
Could someone either tell me if this is not possible to do so, or help me find
what the problem in my options is, please?
