The surface roller model is run after each CMS-Wave and before each CMS-Flow run. It runs on the wave grid but is a separate model and module within the CMS. The surface roller model parameters are set within the CMS-Flow cmcmards for convenience. For more information on the surface roller model see the Surface Roller Technical Documentation.
