NAFEMS Americas and Digital Engineering (DE) teamed up (once again) to present CAASE, the (now Virtual) Conference on Advancing Analysis & Simulation in Engineering, on June 16-18, 2020!

CAASE20 brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, to share experiences, discuss relevant trends, discover common themes, and explore future issues, including:
-What is the future for engineering analysis and simulation?
-Where will it lead us in the next decade?
-How can designers and engineers realize its full potential?
What are the business, technological, and human enablers that will take past successful developments to new levels in the next ten years?

Resource Abstract

Optimizing performance of any electromechanical system requires the ability to accurately capture the dynamics of the interactions between different domains including Multi-body Dynamics, Discrete Element Method, Finite Element Analysis, and Controls & System Simulation. For instance, to accurately predict the mobility of off-road vehicles on soft terrains requires a combined system simulation approach between the electromechanical system, soil, tire, driveline and steering control systems as illustrated in the image below. Accurately accounting for varied soil types to understand soil-machine interactions can accelerate the development electromechanical systems and optimize in-service operation.



This presentation will demonstrate a unique co-simulation approach for high-fidelity product development combining:



1. Bulk material modeling where the number of particles and contacts is not limited

2. Large-scale motion where the number of parts is not limited

3. Flexible Multi-body Dynamics model coupled with DEM for accurate loads and stresses on the equipment

4. Time domain simulation of the system that couples the Multi-body, FEA, Controls and DEM effects
