I need to compute volumes for a 2-D cylindrical mesh of Cell Data, and I’m using V = 2pir*A, where A comes from the Cell Size filter. I can get something close using the Cell to Point filter, but that creates strange visual artifacts at the axis of rotation, probably because everything goes to zero there.

This turns out to be much more straightforward than the previous work-around made it seem. Simply create a calculator for r = coordsX, then run a Point Data to Cell Data filter, to get the axisymmetric radius as a Cell Data field. Then, V = 2 * pi * A * r.
