Hi, could someone please help me out of this problem? I have been struggling with it for weeks now. I don't know what's the proper way of doing surface integration over a sphere which has been defined in cylindrical coordinates due to axial symmetry of the geometry. I have used surf_integral and elevation and I get completely different results, neither of which make sense theoretically. |

In 2D cylindrical geometry, the SURF_INTEGRAL function will weight the integral by 2*pi*R to give a true surface integral of the rotated figure. In the ELEVATION plot, the plotted curve is integrated without geometric weighting.
