Hi,

I am using the Sundials.jl package together with the DifferentialEquations.jl package and I wanted to use the isoutofdomain solver option to ensure that the solver does not try to compute the system state where the position coordinates are negative. I have noticed that in the solver compatibility chart this option is not yet available for the Sundials solvers.

Are there any plans to include that option soon? Alternatively, how could I limit IDA to go into regions where the system is not well defined?

I'm not sure it's possible to control the stepping of Sundials at the level to implement this. I wouldn't expect this any time soon.
