Webb6 juni 2024 · It seems that IAS15 can only handle this down to about e = 1 - 1e-6. I wish IAS15 were better at this, but it's a difficult problem! For example, it's hard to predict the timestep to resolve pericenter, and at some point floating point numbers run out of digits which makes it hard for IAS15 to determine if the integration of converged.
