Menu: View results->Line Thickness
With this visualization, the line elements will be drawn using the result's values as thickness.
This option uses a result component, or a scalar value, and draws the thickness of the lines according to this result. Lines are drawn as a four or eight sided prisms and the selected result is used as a radius of these prisms.
Line thickness is supported for results defined over nodes and over gauss points.
If the gauss points results can be globally smoothed, then a Smoothed sub-menu will be added with a list of the gaussian results, see View Results Menu
The colour of the thick lines can be adjusted with Options --> Result Surface --> Show elevations --> Contour fill, see Result Surface.
