Currently solve lets you set the keyword adaptive to decide whetever the solver should use adaptive or fixed time step methods.
I think this can, for non adapative solvers, lead to undefined behavior?
Either way, i think a more helpfull error message might help the user troubleshooting.
Given a SDEproblem probsolve(prob, EM())
Throws the error: ERROR: Fixed timestep methods require a choice of dt or choosing the tstops
However if I write
solve(prob, EM(); adaptive=true)
shows: ┌ Warning: dt(9.094947017729282e-13) <= dtmin(9.094947017729282e-13) at t=1.3398645121662485e-8, and step error estimate = 1.0. Aborting. There is either an error in your model specification or the true solution is unstable.
