I’m currently doing research in gravitational physics and the problems I’m working with often end up as BVPs that are very stiff and sensitive to the initial conditions. It seems this is still a weak point for Julia’s BVP tools and I was wondering if there was any update on when the BoundaryValueDif…

[image] MButler: It seems this is still a weak point for Julia’s BVP tools and I was wondering if there was any update on when the BoundaryValueDiffEq.jl will see further development? Yes, it’s a weak point of SciML. But we have a pretty grand plan for fixing it. Most BVP solvers specialize t…

Yes, that’s part of the same whole thing I mentioned above.

[image] MButler: BVPs that are very stiff and sensitive to the initial conditions Can you explai this setence please? In BifurcationKit , there are 2 ponits BVP solvers but there are a bit hidden because I focus on computing periodic orbits, they work in large dimension. THere is even the sta…

Thank you for the update and giving some insights of where things are going. [image] ChrisRackauckas: Yes, it’s a weak point of SciML. But we have a pretty grand plan for fixing it. Most BVP solvers specialize too much on ODE 2-point boundary problems, or lose any specialization. This is pro…

[image] MButler: This is probably my biggest complaint of other bvp solvers out there. They often become far too specialized on a specific problem or class of problem. I only have a general understanding of MIRK methods. Do you have any references I could look over in regards to the techniques …

Update on future developement of BVP solvers?

While we’re discussing BVPs, SciML currently doesn’t handle BV DAEs.
Other solvers like Coldae.f etc do.

Would also be nice at some point
