Generation of Random Surfaces

Application ID: 50281

These examples demonstrate how to generate randomized geometric surfaces. The COMSOL Multiphysics® software provides a powerful set of built-in functions and operators, such as functions for uniform and Gaussian random distributions and a very useful sum operator. In the blog post associated with these files, "How to Generate Random Surfaces in COMSOL Multiphysics", we show you how to generate a randomized surface with what amounts to a "one liner" expression with detailed control of the constituent spatial frequency components that determine the nature of the surface's roughness.

This application example illustrates applications of this type that would nominally be built using the following products:
