May 23, 2001, 12:11	Calculate circulation	#1
Beginner Guest Posts: n/a	Dear all I try to calculate the strength of circulation from velocity field. I know that the strength of circulation is the integration on close curve of the dot product between velocity vector, V = ui + vj, and little distance vector, say dS = (dx)i + (dy)j. How to do this numerically?
