Any of the above allows you to specify whether or not results will be averaged at element boundaries where
material and/or real constant discontinuities exist. For more information, see PowerGraphics (p. 235).
Caution
If PowerGraphics is disabled, you cannot use the AVRES command to control averaging, and the
averaging operation is performed at all nodes of the selected elements without regard to the
attributes of the elements connected to them. This can be inappropriate in areas of material or
geometric discontinuities. When contouring derived data (which are averaged at the nodes), be
sure to select elements of the same material, same thickness (for shells), same element coordinate
system orientation, etc.

See the PLNSOL command description for further information.
Figure 7.2 Contouring Derived Data with PLNSOL
The PLESOL command produce contour lines that are discontinuous across element boundaries. Use this
type of display mainly for derived solution data. For example:
