It’s been a while since I looked at this; as I never really got my head around this, in the meantime, you could try a simple discretization approach, so this isn’t a blocker. See [Help with speeding up large ODE system from ModelingToolkit - Specific Domains / Modelling & Simulations - Julia Programming Language (julialang.org)](https://discourse.julialang.org/t/help-with-speeding-up-large-ode-system-from-modelingtoolkit/98903/1), although the simplification takes quite a while.
