comment How to speed up execution of this function?
Isn't HarmonicNumber[n, s]//N faster than Sum[m^-s, {m, 1., n}]?

comment How can I operate the (direction of) arrows in ContourPlot separately?
If all you're trying to do is to draw arrows in the contour lines, why did you post your full problem? Just make up a fake and simple CountourPlot[] and re-ask without all the burden

Welcome to Mathematica.SE! I suggest the following: 1) As you receive help, try to give it too, by answering questions in your area of expertise. 2) Read the faq! 3) When you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge. Also, please remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign!

comment Help needed for solving nonlinear ODEs
I think the above comments summarize all that can be said with the information you provided. Solving DEs is a huge topic with many subtleties and apparently you're starting with Mathematica. There are no general recipes.

comment Speed up calculation
@MilenkoRubin-Zuzic That's probably because I'm using a syntax variant for Fold[] with two arguments instead of three. Not documented but cool :)

The output you're getting seems the right answer. What do you expect?
