``` # This example using BVProblem with solver RadauIIa5 is based on # an attmpt to reproduce the analytic solution... # y(t) = t^2 + 10. using BoundaryValueDiffEqFIRK function f!(dy_dt,...

Could you please tell me where I might find a list of documented features that are unsupported by this solver at this time? (Maybe I should just give up on...

One more point — the MWE in my last post does not trigger ForwardDiff. I inserted this global… ``` function f!(dy_dt, y, par, t) global typeofy = typeof(y) ``` to...

**Another possibly unimplemented feature of RadauIIa5** Its description [here](https://discourse.julialang.org/t/error-with-forwarddiff-no-method-matching-float64/41905) says ... ``` For type-stability, the chunksizes for ForwardDiff ADTypes in BVPJacobianAlgorithm must be provided. ``` so I tried... ``` sol...

**Regarding priorities**... Let me note here that it is **not** urgent for me to have access to the derivative calculations such as ``` resid[2] = (soln(1.0,Val{2})[1] - 2.0) ``` as...

Thanks, but nope... ``` sol = solve(prob, RadauIIa5(autodiff = AutoFiniteDiff() ); dt = 0.1, abstol=1e-6, reltol=1e-6) ``` ``` ERROR: MethodError: no method matching RadauIIa5(; autodiff::AutoFiniteDiff{Val{:forward}, Val{:forward}, Val{:hcentral}, Nothing, Nothing}) This...

ohK!
