Hello Mario, try this example please: a = 3 b = 5 v = 7 llimit = v/(Pi*b^2) Plot3D[Sin[l*r], {r, a, b}, {l, 0, llimit}] As r cannot exceed b you can replace r^2 by b^2 in llimit. Adjust the a, b, v to achieve the degrees of difference (<,>) you want. Best regards, Matthias Bode Sal. Oppenheim jr. & Cie.

Any idea of how to do that.
