Using integration coupling variables

$

Dear all and Ivar Kjelberg,
I used to integration coupling variable--->Point variables in order to derive integration velocity (u) and I got displacement (dr) in results for the case of 2D. But right now, my direction research is in 2D axisymmetric. Of course, if I used the integral equation similar to the case of 2D, the displacement results will be wrong.
Does anyone can give me suggestion about integration velocity equation in 2D-axisymmetric? I used moving mesh coupled with heat transfer and laminar two-phase flow, phase field.
Thanks so much!!!!
