Solver option save_idxs not supported for PDE indexing.

[jbiffl]

Discretized PDEs generate dict-based solutions of the form sol.u[dv(iv1,iv2)][idx1,idx2] which do not allow use of solver option save_idx = [idx_n].

This makes parameter fitting more challenging and would be a very great feature to get back.

@xtalax have you played with save_idxs at all? The PDE solution is placed too late, so it would miss the dispatches

I have seen this. Can we discuss next week?

[ChrisRackauckas]

Yes
