Draw the current mesh. In general, the grid lines are drawn in a standard color (white or black). However, if [Procs] is selected from the [DoF]-submenu, the grid lines are colored according to the processor number, and for [Mater] the grid line colors correspond to the material numbers. The [Net-2D]-submenu will change either to [Tensor] (draw small crosses) or [Vector] (draw small arrows) as decribed in the [Tensor]-submenu of [Options].
