Hi Erno, I am afraid that points=:specified is currently not supported by ODE.jl. There is a PR for adding ode23s (stiff solver) <https://github.com/JuliaLang/ODE.jl/pull/47>, which supports it. So if you need/want it now you might try that fork. As Ivar says we are discussing how points=:specified should work in the future (mainly #40 <https://github.com/JuliaLang/ODE.jl/issues/40> and #43 <https://github.com/JuliaLang/ODE.jl/issues/43>) and any input/insight is welcome!
Best, Alex.
