comment Solving a nonlinear, second order d.e. in Mathematica
@LeonidShifrin NDSolve stiffness, story of my life! I found that using Method->"LSODA". I let the "MaxDifferenceOrder" "float". Given your hightened understanding of this problem, do you have any comment on my positive experience with "LSODA"?

Very interesting! I'll see how this cranks out on my computer.

comment How to demonstrate lack of stability with advection equation
Why when I increase the MaxPoints while holding MinPoints constant, does the error increase? I would assume the reverse should happen...

Thank you. So is it difficult to back-out a "CFL" number out of this example when one uses mathematica since mma always "sets/adapts spatial grid resolution"?
