The attached screenshot shows the modal analysis of a longitudinally resonant cylinder (30 degree segment). The Z_displacement is highest at the centers of the top and bottom surfaces. The physics of such a vibrating cylinder requires that there must be a plane at mid-length where the Z_displacement is zero. I need a way to set the color bar's min value to zero, even though this might not be available from the FEA (due to interpolation or other).
(My ultimate goal is to normalize the values on the color bar so that they range from 0 to 1.0.)
Thanks,
Don C.
