Hey there, I’m trying to compute the derivatives of a function involving an ODE solution. This works if I use dense Jacobians in the ODE solver. However, the Jacobian is actually sparse (PDE discretization, stiff) and I thought to exploit that: using DifferentialEquations, ForwardDiff, SparseArra…

Computing ODE sensitivities with sparse Jacobians in solver

You’ll need to switch to SparsepakFactorization(), which it should do automatically?
