Consider the classical stiff ODE system  It is easy to declare the ODEProblem in julia by following codes with the is-inplace form ```julia function f(du, u, p, t) du[1]...
[Lorenz example from the docs](https://docs.sciml.ai/DiffEqDocs/stable/getting_started/#Example-2:-Solving-Systems-of-Equations) has type instabilities both in the problem definition and the `solve` call. ``` function lorenz!(du,u,p,t) du[1] = 10.0*(u[2]-u[1]) du[2] = u[1]*(28.0-u[3]) - u[2] du[3] =...
**Describe the bug 🐞** Solving an ODE with nested structs is type-unstable. **Expected behavior** Julia's compiler should be able to fully infer the type of the `ODESolution`. **Minimal Reproducible Example...
[`ComponentArrays.jl`](https://github.com/jonniedie/ComponentArrays.jl) is very helpful to handle states and parameters and works well with DifferentialEquations (e.g. plots are automatically labeled https://github.com/SciML/DifferentialEquations.jl/issues/617). Unfortunaly, it seem we lack a good interface to extract...
# Bug and MWE The following problem does not solve (i.e. gives `Warning: Newton steps could not converge and algorithm is not adaptive. Use a lower dt.`) ```julia using OrdinaryDiffEq...
Greetings, I tried to simulate the electronic buck converter using the following code: ``` using DifferentialEquations using Plots function odeDiffEquPackage() function f(du, u, p, t) C = 1e-4; L =...
Thanks to Ian Butterworth, `julia-actions/cache` caches `~/.julia/compiled` too (https://github.com/julia-actions/cache/pull/71). Maybe interesting for the SciML ecosystem.
Is it grammatical to construct a system of differential equations in this way? What does this error mean? function eee!(u, p, t) x, y = u a,b,c = p for...
With this issue I would like to get the discussion about a PDE/PDAE interface for the DifferentialEquations.jl ecosystem started. I should also note that I might be quite biased, because...
Trying out a DynamicQuantities.jl example with DifferentialEquations.jl but running into some issues with the use of `oneunit(::Type{T})` rather than `oneunit(::T)`. I think changing to the latter will make things compatible...
