I have a simple 3-species food chain that I would like to run for 200 steps so the system stabilizes. I would then like to start harvesting and show how populations fluctuate. Is there a way to do this? The natural/non-harvested system is: using DifferentialEquations f = @ode_def_bare Pristine b…

The issue is that you used the argument callbacks instead of callback. That was my bad (and we really need to error for that). A corrected code is: using DifferentialEquations f = @ode_def_bare ManagedLinear begin dBB = r*(1- BB/K)*BB -xI*yIB*BI*((BB^h/(B0^h + BB^h))/eIB) dBI = -xI*BI + xI*yIB…

Is there a way to run differential equations to a specific point and then change input values, continue running, and graph it together?

The easiest way is to just make it a single diffeq solve with a callback that implements the change.

What does "user_cache: method has not been implemented for the integrator" mean?
