Hello, I would like to use Symbolics.jacobian_sparsity to detect the sparsity pattern for a code that supports ForwardDiff.jacobian using PreallocationTools. The code below is a MWE for a program where the full residual array dae.f is incrementally built by evaluating multiple functions res1 and r…

[image] cuihantao: I found a workaround by duplicating the data with the field types being Num. The code below is my workaround, and that is no where close to an ideal solution. Yes exactly, that can be a solution. Or just a fallback Any mode
