Contact Surfaces
Contact surface entities define and store contact definitions typically used in contact analysis.
Contact surfaces are defined using elements (1D/2D/3D) and their respective facecodes. A contact surface is displayed as an arrow on the selected element faces in the modeling window. The direction of the arrow is along the element normal that defines the contact surface.
