Introduction to Particle Modeling using the Discrete Element Method

Course Duration: 2 Days

Prerequisites

STAR-CCM+ Experience

Who Should Attend

This training course is appropriate for engineers who wish to refine their simulation analysis skills within the particle modeling application area and is appropriate for various industrial applications such as oil and gas applications, pharmaceutical applications, civil engineering, hydraulic engineering etc.

Course Description

The purpose of this course is to introduce advanced engineering techniques needed to investigate typical analysis problems involved in the coupling of continuous flow models and the motion of discrete solids or particles phase. The class structure will introduce engineers to the philosophy behind Discrete Element Modeling, the background and applicability of the approach, and the methodology used to solve the analyses in engineering situations. Students will also examine the differences between DEM and classic Lagrangian approaches in order to determine the most effective approach to achieving success in real world engineering analyses. The course is structured as a combination of lectures and hands on workshops (tutorials), with users generating a complete analysis for five different engineering applications. Attendees will learn how to set up, run, and post-process these DEM specific simulations in order to make engineering decisions on new and existing designs. At the end of the class, engineers should be comfortable with the tools used in this analysis process and be able to begin applying the techniques to their own analysis situations with high levels of robustness, accuracy and repeatability.
