Multi-language suite for high-performance solvers of differential equations and scientific machine learning (SciML) components. Ordinary differential equations (ODEs), stochastic differential equation...
It works for the following set of parameters: ```julia using DifferentialEquations, Plots; function ngm!(dX, X, θ, t) C, K = X ρ, γ, z, α, δ = θ dC =...
I have a simulation where zero crossing gives a wrong result. Its hard to construct a simple example with this effect, but the reason for this issue can be clearly...

The FunctionCallingCallback seems to be not correctly synchronized with events as shown with the following test model: ``` module Test_bouncingBall_withFunctionCallBack using DifferentialEquations function f(du,u,p,t) #u[1]: height, u[2]:velocity du[1] = u[2]...
It can be nice to use `Rational` numbers in `PeriodicCallback`s if you have a bunch of different discrete things that fire at different rates. That way you can take the...
# Take awhile to precompile with style all of the DiffEq stack, no denial Our goal is to get the entire DiffEq stack compile times down. From now on we...
Fairly regularly (in teaching) I need to turn a second order ODE to a first order one. I'm surprised tuples can't be used to do this, see below. I also...
I am trying to use the Lokta-McKendrick equations with the Differential Equations packages. But I am stuck while trying to transform the system of equations into a form suitable for...
Greetings, I was surprised to see *very* slow solution times when using callbacks (~4x slower) even when those callbacks do nothing of interest. In trying to produce a minimal example...
Hi, When passing kwargs to `solve` I am surprised that they can't be recovered from the solution ``` sol = solve(prob, Tsit5(); reltol = 1e-5) ``` Where is `reltol` saved...
