Surface interaction is an important topic in engineering, and it is generally recognized that the roughness of a surface has a significant impact on numerous physical phenomena, including contact, wear, friction, and heat transmission.

Nonetheless, generating rough surface models with Abaqus/CAE is quite challenging and may necessitate the usage of auxiliary tools. I present a plug-in called RSGen for automatic finite element model generation of rough surfaces in an Abaqus/CAE. RSGen supports all accessible Abaqus elements, from 2D-wire to 3D-solid. The rough surface can be constructed by importing the measured surface profile data as a text file or by entering geometrical parameters through a graphical user interface.
