Learn about common errors to look out for in results
Post processing results from finite element analysis (FEA) solutions is essential to understanding whether your design passes or fails based on your engineering criteria. There are many options available for checking the design integrity, such as different types of stress plots. There are also several contour options such as nodal, elemental, max, and average. During this course we'll explain the importance of all these options and what to look out for to make sure the results are accurate.
This course is for the design / engineer who would like to have a deeper understanding of the results that come from FEA.
Jim Byrne has 17 years of experience marketing, selling, and supporting CAD solutions for engineering and manufacturing. For the past 2 years he has been the technical marketing specialist for Simulation Mechanical software, Autodesk Nastran InCAD software, and Simulation CFD software.
Real-world problems are rarely linear or static. Nonlinearities often impact the prediction of a product's behavior in unpredictable ways. These add uncertainty and risk to decisions made from either virtual or physical test results for engineers and designers who don't understand them. We will summarize simply and clearly the process of identifying and planning for the 3 key types of nonlinearity in product performance so that all attendees will be able to spot them, again in both physical as well as virtual testing. We will teach you how to account for nonlinearities in testing, but the remaining focus will be on nonlinear simulation covering processes, terms, and troubleshooting. While we will use Simulation Solutions for illustration, the concepts covered will be valid for any simulation software attendees.
In this class, Autodesk Simulation experts will examine the commonly understood, and often published, methods for modeling welds in finite element analysis (FEA). The true nature of welds, their physics, material characteristics, and failure modes will be reviewed in the context of what you can and can’t expect from simulation. Best practices for static weld sizing using FEA, primarily Nastran In-CAD, and Inventor will be revealed. Evaluating welds for fatigue will also be reviewed to ensure participants are using state of the art simulation for all their welding applications.
This lab will focus on getting started with Autodesk Nastran In-CAD software inside of Inventor 2016 software. Participants should have an understanding of finite element analysis (FEA) and the preferred participants are currently using FEA in their jobs. We will explore the Ribbon, Browser, and different analysis types. We will have a few workflows for basic users that are looking to crest the initial hurdle when learning new software, as well as a few examples for the more advanced users who are familiar with FEA software.
When performing finite element analysis, the quality of your mesh dictates the accuracy of your results. With the advances in automatic meshing technology, this quality is often overlooked. This class will focus on key topics such as selecting the correct mesh size, using mesh refinement, and interrogating the element quality to make sure you can be confident in your results.
