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 model example illustrates applications of this type that would nominally be built using the following products:MEMS Module Structural Mechanics Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
