Yeah, I totally agree. This is entertaining until it becomes annoying methinks. In any case thanks a lot for your help

comment Why does Arrow not work well with Scaled coordinates in 3D?
Thanks! The reason I am using scaled coordinates is that it's really easier to annotate a plot with them. I have upvoted and plan to accept this. My only reservation is that if the plot range is a bit uneven weird things happen to the arrow head despite the scaling: Show[Plot3D[Sin[(x - y)/40], {x, 0, 30 π}, {y, 0, 30 π}], Graphics3D[{Arrowheads[{{.02, 1, {Graphics[Polygon[{{-1, 1/2}, {1/2, 0}, {-1, -1/2}, {-8/9, 0}, {-1, 1/2}}]], 7/9}}}], Arrow[Scaled /@ {{0, 0, 0}, {.9, .9, .9}}]}]] (this is not to do with your answer, it is happens anyway and is more prevalent with Tube)

I've added a bit but I don't know if I made it more or less clear :)

@Jens ah, I should have looked on your website before asking. If you can find the time that would be great but it's not a pressing issue - I was just puzzled by this.

Mind you, my solution also rounds it up to whatever resolution you pick.

revised NDSolve: Couple ODE and PDE
Some spelling and syntax and replaced the code from a comment.

comment NDSolve: Couple ODE and PDE
Sorry I can't make sense of this as there are a bunch of brackets missing, all the variables have been switched to [Theta], [Omega] in place of \[Theta], \[Omega] and a constant isn't defined. You could edit the question with the full problem - that would help people get interested in this.

Can you post a minimal example capturing the intricacies of the original problem then?

Can't you just integrate your n function by hand and explicitly add it to the equation?
