Use of save_idxs solver option with MethodOfLines/ModelingToolkit

Specific Domains Modelling & Simulations

I’m trying to use save_idxs to facilitate parameter fitting and while I’ve figured out that my solution needs to be accessed after solving as:

sol.u[var1(x,t)][idx1,idx2]

I’m having trouble figuring out how to use the save_idxs=[idx_to_be_saved] solver option.

Is there new syntax for this?

Open an issue. I don’t think that works with the PDE indexing right now.

Okay, will do. Since save_idxs is from the DifferentialEquations.jl package, I will open it there.

Thanks!
