When I run the very simple MWE posted below containing BVProblem which specifies solver RadauIIa5, it runs with a return code “Unstable”, and produces unexpected all-zero results. In view of the simplicity of this problem, I wonder what I might have done wrong. I would appreciate it if you could i…

function f!(dy_dt, y, par, t)

dy_dt[1] = 2.0 .* t

end
