Visualization of 3-D surface roughness and contact

A Live Script for visualizing three-dimensional contact between surfaces of different roughness.

A Live Script for visualizing three-dimensional contact between surfaces of different roughness:

Assumptions: Surfaces are parallel, stationary, non-interacting, and non-deformable. The probability density function to describe the asperity height distribution is conserved across the length and width dimensions of the interface.

User inputs: Interface dimensions, probablity density function of asperity heights for each surface, nominal surface separation.
