I am playing around with the capacity of changing the size of an ODE system by tweaking the example presented here . For some reason, shrinking the model by resize!()ing the integrator works as expected, but the (equivalent?) deleteat!() fails with a “DimensionMismatch” or a “BoundsError”. using Dif…

It works when you specify the algorithm: using DifferentialEquations using Plots const α = -0.3 function f(du,u,p,t) for i in 1:length(u) du[i] = α*u[i] end end function condition(u,t,integrator) # Event when event_f(u,t) == 0 minimum(u)-0.01 end function affect!(integrator) u = inte…

Thank you for the reply, I will look into it. And yes from reading the docs I also had the impression it should work, maybe a bug indeed.
