To obtain better simulation results, a systematic and powerful mesh is key. While some finite element analysis (FEA) software products have advanced meshing tools to help obtain a superior analytical model, applying these tools can be complicated. Using the guidelines and tricks taught in this session upfront, during your CAD modeling for simulation with Autodesk software, you can develop a better mesh more efficiently and obtain accurate and precise results. This class will explain first how to recognize mesh qualities, then how to use CAD modeling techniques to obtain a refined mesh more efficiently, saving time and money in your analysis efforts.
The Simulation workspace in Fusion 360 software has been evolving at a rapid pace. In this hands-on lab, you’ll get experience setting up and solving all of the study types in Fusion 360. If you’re new to Fusion 360, this will be a great opportunity to see all that the Simulation workspace has to offer. If you are new to Simulation, this will be a great opportunity for you to see how easy it is to start improving your designs.
In this class, we will discuss methods for working with real-world designs and preparing them for efficient Simulation. Many common design practices often create headaches for quickly evaluating the performance of a design. We will look at simplification techniques for dealing with purchased parts, creating simulation variations to look at what-if scenarios and understand best practices for working with thin-walled designs. Lastly, we will provide you with some tips and tricks for getting the most of our Simulation in Fusion.
As success and comfort levels increase, engineers need to look beyond the limited questions that can be asked of this linear static solution to truly understand and respond to the demands of innovation. Autodesk Nastran In-CAD software brings advanced analysis techniques to the Inventor platform, letting engineers explore nonlinear, vibratory buckling and other behaviors or failure conditions within the context of an interactive design and modeling session. You will learn to recognize the need for these solutions and how to take your Inventor digital prototypes through advanced tests. Additionally, you will be introduced to the inputs required and the outputs produced so more-exacting and more-precise engineering decisions can be made.
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'll summarize simply and clearly the process of identifying and planning for the 3 key types of nonlinearity in product performance so that you will be able to spot them in both physical as well as virtual testing. We'll 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'll use Simulation Solutions for illustration, the concepts covered will be valid for any simulation software attendees.
This class will explore the computer-aided thinking and design process that the Nairobi-based Engineering Team from a leading social enterprise uses to create new, income-generating products for the poorest segment of Africa’s population: small-scale farmers. Developing irrigation products that are affordable and uniquely tailored to the complex needs of small-scale farmers in Africa is a design challenge with the potential to improve the lives of millions. Examples from the work of KickStart International will illuminate how Inventor software, Simulations Mechanical software, and Autodesk CFD software are used to address this challenge more efficiently. KickStart has been expanding their line of human-powered irrigation pumps for more than 15 years, and the introduction of Autodesk, Inc., software and 3D printing have improved workflow by shortening the concept-to-completion product-development cycle and offset some of the challenges of prototyping and batch producing locally, in Kenya, on the way to mass manufacture. This session features Inventor Professional, CFD, Fusion 360, and Simulation Mechanical.
Moldflow Insight software is used to develop automotive interior and exterior in China’s Chang’an Automobile Group, from the stage of engineering design to part's structure design then to mold design and molding condition optimize also include the trouble shooting after the first trial. Based on the comparison between the experiment and Moldflow Insight results, Chang’an successfully built an analysis standard and results judge standard. With the help of API, Chang’an created many programs to automatically do the model create, molding condition optimize, results judge, and so on. To meet the assessment criteria of GDT which was used on the part of motor, normally defined the tolerance of fit. Changan's analyst explore and studied a new way to simulate and examine the part's GDT by co-work with Moldflow Insight, Digimat, and Abaqus. This class will use many actual case to show these application, through that we can see the benefit of use right Moldflow Insight application strategy in the development of automotive interior and exterior new part.
Traditionally CAD and CAE have mostly been used for documenting designs and providing feedback on how they perform in operation. Improved tools, expanded computing power, and new manufacturing technology are now opening up new possibilities for computational design and engineering, where CAD and CAE are used to actually generate part geometry directly. These tools help engineers explore an array of design strategies and create lighter, stronger, or more-efficient parts by driving the design with functional goals, not just a handful of dimensions on a sketch. This course will provide some context for optimization tools as they exist today and introduce several new tools aimed at this goal-driven design concept.
This class will walk though techniques for preparing geometry for simulation using SimStudio Tools. We'll cover hints that will help you to identify potentially problematic areas, and then we'll show you how to quickly repair models, remove unneeded detail, and optimize the geometry in a way that will help you to create a high-quality finite element analysis (FEA) or Computational Fluid Dynamics (CFD) mesh.
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.
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.
Simulation tools are transforming the field of aerospace design by enabling affordable, on-demand simulation capabilities. Escape Dynamics, Inc., has been actively using mechanical and computational fluid dynamics (CFD) simulation tools in the design/optimization process of several key components of their space launch system, including antennas for wireless energy transfer, airframe and structural components of a single-state-to-orbit space plane, and a highly efficient combustion-free engine configured to use wireless microwave energy to power a space plane. In this lecture we will summarize the key benefits of using Simulation software tools in aerospace design application, and we’ll focus more narrowly on the CFD and mechanical simulations of our thermal thruster engine. We will specifically focus on comparison between simulation results and the real-world test data and share the lessons we've learned in simulating various heat-exchanger topologies, flow-through nozzles and pipes, and flow-with-heat addition.
