This talk will present how the integration of Autodesk Nastran software, Helius PFA software with Advanced Material Exchange (AME) capabilities, and Moldflow software work together in the real world of complex composite simulations. Composite materials are an advanced family of materials that have been in development for decades and continue to gain usage in the aerospace, marine, automotive, and sporting goods industries. While composites enjoy benefits such as high strength-to-weight and stiffness-to-weight ratios, they are considerably more complicated than most metals and plastics. Helius PFA with its AME capabilities is part of the Autodesk Solution for digital prototyping, and it provides fast, accurate, and flexible tools for enhanced finite element analysis (FEA) of composite structures-manufactured from unidirectional or woven composites to injection-molded, short-fiber filled composites-including progressive failure analysis to help reduce testing and shorten design cycles by identifying potentially unforeseen design and material deficiencies.
Analysts, designers and managers who are interested in incorporating progressive failure techniques and as manufactured material properties into structural analysis of composite materials.

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.
This presentation will focus on the newly developed Topology Optimization technology now being used in Autodesk Nastran In-CAD software and also found in Autodesk Nastran standalone, Fusion 360 Ultimate software, Inventor Simulation software, and Dreamcatcher software. We will begin with an introduction of how Topology Optimization works, and then we'll focus on the Autodesk Nastran In-CAD interface for Topology Optimization. We will perform several examples that will include how to produce designs with minimized mass and maximized stiffness that comply with various design and manufacturing constraints. Examples will include minimized mass with stress and compliance design constraints and various manufacturing constraints such as additive and subtractive with symmetry. We will show a complete workflow that includes importing optimized .STL geometry and building a verification analysis model.
Multiaxis, large-scale 3D printing opens the doors to new application fields for engineers, architects, designers, and scientists. For this, the Netfabb and PowerMill high-rate technology combined with Autodesk tools like Autodesk Nastran software, PowerInspect software, Inventor software, and Fusion 360 software create new possibilities in design and manufacturing. This class will also cover examples from our industrial and research partners and show a workflow for high-rate deposition.
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 dives into our cross-divisional project at Autodesk for the making of a SmartBridge inside our Pier9 facility.We'll walk through our case study where we used structural analysis, Eagle, Revit and Forge to design and plan the layout of sensors onto an interior pedestrian footbridge. Using sensors for strain, acceleration, temperature, pressure, humidity, sound and cameras, we created the "nervous system". We then integrated all this live sensor data into Autodesk's cloud environment, and used Forge to bring all the data into one context on top of the BIM.Using data at the centre, we'll show you how we learned from the data to create various machine learning analytics for interacting with people on the bridge. In our class, we'll go over how we applied big data analysis techniques, machine learning, computer vision and visualization in the cloud to make our bridge "smart".(Joint AU/Forge DevCon class).
