Hi,

I’m trying to solve a system of equations where some of the terms have explicit dependence on dt.

The way round this I am using is passing dt as a parameter:

```
params = Dict(:dt => dt)
params = NamedTuple(params)
bvp = BVProblem(f!, bc!, init, (0,1), params)
sol = solve(bvp, MIRK4(), dt=dt, adaptive=false)
```

How can I make use of adaptive solvers here? I don’t entirely understand the behind-the-scenes of this so may have an error of understanding! Is it possible at all?
