Advanced Seminars
Topics Include:
Leveraging the Latest Solver Technology in Abaqus for Challenging Static and Dynamic Applications
- 1/2 day: Implicit Dynamics
Pavel A. Bouzinov, Ph.D., P.E., Principal
Development Engineer
Nonlinear implicit dynamics is useful for many industrial workflows–especially as a result of recent enhancements to improve accuracy, robustness, and performance for truly dynamic and quasi-static applications. Attend this seminar to learn about methods and techniques that can be used to solve complex dynamic problems and how to use implicit dynamics to improve convergence in difficult static problems. Topics include characteristics of various numerical time integrators, damping techniques, solution accuracy, contact considerations, and tips for improving convergence.
- 1/2 day: Using Iterative Solver Technology and High-Performance Computing with Abaqus/Standard
Vladimir Belsky, Ph.D., Director of Solver Development, Implicit Analysis – Solvers, SIMULIA
In this advanced seminar we will mainly focus on various aspects of the new iterative solver technology that was first introduced in Abaqus/Standard with version 6.9-EF. This technology is often misunderstood and attempts to utilize it in far from ideal situations have left many analysts disappointed. Therefore, this advanced seminar will make an attempt to set reasonable expectations through a detailed look at the pros and cons as well as the applicability areas of this technology.
In particular, we will first describe the need for this technology and demonstrate applications where direct sparse solver technology is computationally too expensive or simply impossible to use. Then we will go over various modeling practices that are required to take advantage of this technology by using detailed case studies.
In addition to iterative solver technology, we will go over relevant HPC topics such as hardware configuration and simulation cost analysis and finally discuss future HPC trends in simulation technology. These final topics will cover broader ground within SIMULIA's product family.
Solving Challenging Contact Problems with New Capabilities in Abaqus
Harry Harkness, Director for Contact Development, SIMULIA
Contact interactions between different parts play a key role when simulating bolted assemblies, manufacturing processes, dynamic impact events, and various other systems. Accurately capturing these interactions is essential for solving many engineering problems. SIMULIA has developed state-of-the-art contact modeling capabilities in Abaqus. Attend this seminar to learn the latest techniques and strategies for solving difficult contact problems with Abaqus. This seminar will primarily focus on Abaqus/Standard, with additional discussion of Abaqus/Explicit. Topics include advantages of the general contact capability, obtaining accurate contact pressures, insight on numerical methods, tips for improving convergence, recent enhancements to the implicit dynamics procedure for contact models, and properly representing physical details associated with contact.
New SIMULIA Technologies for Multiphysics and Co-Simulation
Karl D’Souza, Product Manager, SIMULIA Strategic Planning
Multiphysics analysis continues to gain greater acceptance in the industry. As a result, companies have evolved their simulation methods to a point where they are able to make fewer approximations and obtain more realistic predictions of coupled physics phenomena. In this seminar, you will learn how to analyze a variety of complex multiphysics problems, and gain experience through examples including fluid-structure interaction (FSI), thermal-mechanical, structural-acoustic, and structural-piezoelectric interactions. Special emphasis will be given to FSI and will cover the Coupled Eulerian-Lagrangian (CEL) approach in Abaqus/Explicit, the new computational fluid dynamics (CFD) capability in Abaqus, and the ability to couple Abaqus with third-party CFD products.
Performing Process Automation and Design Optimization with Isight, Abaqus, and Other Tools
Charles Yuan, Senior Engineer, SIMULIA
This seminar will illustrate how Isight software can be used to create better-performing designs that work in the real world. Attendees will learn how to set up CATIA, Abaqus/CAE, Abaqus/Explicit, and Abaqus/Standard models in Isight and how to combine these models with in-house codes as well as Excel spreadsheets.
The course highlights the various technologies used to drive the behavior predicted by these automated simulation tools to their design target performance. These technologies include: Design for Experiments, Approximation models, single- and multi-objective Optimization, and quality engineering methods such as Monte Carlo simulation. All of these methods are combined into a single, repeatable, realistic, optimal design process that deploys company resources (human, hardware, and software) in the most efficient way.
During the class the presenters will give live demonstrations of the Isight software.
