All, While plotting vorticity contours in plotStuff, I noticed it was not be plotting the entire vorticity field. You are given the options of vorticity, xvorticity, yvorticity, and zvorticity; both the vorticity and the zvorticity plots show the same contours. Should the regular vorticity option plot the combined contour field of the rotation in all three planes, and not just the z plane? Kyle Hord
