Methods for Generating Rough Surfaces in ANSYS

Many engineering fields, including tribology and MEMS, seek to use or alter the behavior of the system at the surface or at the interface between surfaces. Thus, the topography of the surface is of great interest and must be included in finite element simulations. Four methods for generating normally distributed rough surfaces using APDL are proposed. The resulting geometry, meshes, and solutions are then compared to demonstrate the strengths and weaknesses of the various methods.
