Multi-language suite for high-performance solvers of differential equations and scientific machine learning (SciML) components. Ordinary differential equations (ODEs), stochastic differential equation...
**Is your feature request related to a problem? Please describe.** Iām modelling cell population dynamics. Cells die and divide so the size of system is always changing. Most of my...
**Describe the bug š** When solving the Fitzhugh Nagumo equation on https://docs.sciml.ai/ModelOrderReduction/dev/tutorials/deim_FitzHugh-Nagumo/ using the single argument `solve` call, I get a MethodError. I don't get the error when I specify...
**Describe the bug š** My state variables are expressed with the VectorOfArray structure of RecursiveArrayTools.jl and I want to solve a system of matrix DAEs expressed in a Mass-Matrix Format....
**Describe the bug š** I am solving a SteadyState ODE problem with the DynamicSS solver using QNDF and the solver gets stuck when setting both abstol and reltol very small....
Hello! I hope that you can help me with this problem I have been having using this amazing library. I am working on a problem that involves simulating SDEs for...
As a bit of an extension to the discussion in https://github.com/SciML/DifferentialEquations.jl/issues/1082#issuecomment-2779091824, specifically on the DifferentialEquations.jl changes, we need to consider what we want DiffEq to look like. We can do...
**Describe the bug š** First, I'm sorry to write such a relatively low-quality issues without any reproducers, but in spite of some effort, I could not get any small example...
**Describe the bug š** When the integrator is stepped following parameter mutation with integrator.p, the old value of params is used for 1 timestep. **Expected behavior** The step after parameters...
**Describe the bug š** I would like to use ForwardDiff to calculate the sensitivity of an ODE system using a split problem. It currently works with an out-of-place ODE function,...
As SciML has grown, so has its structural needs. Back in 2017, we realized that DifferentialEquations.jl was too large and so it needed to be split into component packages for...
