The ODESolve() function in Prime uses Adams/BDF by default (as the documentation says). This is not manually selectable to the other algorithms by the user. I have several cases where the Adams/BDF solver (it may be defaulting to BDF - I can't tell) is orders of magnitude less accurate than the same equations solved in Mathcad 15 using rkfixed as the selected algorithm.
Mathcad Prime should allow a dropdown or extra parameter on ODESolve for selection of the algorithm to be used.
