For high-performance HVAC systems such as radiant heating and cooling, underfloor air distribution (UFAD), and natural ventilation and hybrid systems that use both natural and mechanical conditioning of a building, it is critical to understand how the air flows and the surrounding environment impacts the occupants' comfort while still being able to balance energy savings. Computational Fluid Dynamics (CFD) models are key to understanding this balance. This class will teach you how to prepare an Autodesk® Revit® 2013 model and import into Autodesk® Simulation CFD 360 software. From there, you will learn how to quickly create wind-driven models of the airflow around the exterior of a building. You will also learn how to create buoyancy-driven steady-state models to understand the airflow and surface temperatures to provide design recommendations to increase thermal comfort. You will leave this class with the skills to use your CFD model to optimize your building and achieve energy savings for your high-performance HVAC system.
Engineers who are interested in diving into detailed CFD analysis and modeling for a more sustainable and informed design
Detailed analysis of mold designs is becoming increasingly necessary as advanced mold technologies are adopted. Conformal mold cooling is a cooling technique that aims to offer optimal cooling conditions exactly where you need them. The technology has been around for many years, but has become a real option now with the better and cheaper ways to manufacture conformal cooling cores. Hot runner systems are very commonly used in plastic injection molding. Although these are simple systems on the surface, what actually happens inside the hot runners and how they lose heat into the mold can be quite complex. With the Cool (FEM) functionality inside Autodesk Simulation Moldflow software coupled with Autodesk® Simulation CFD software, you now have the capability to model even the most complicated conformal geometries and hot runners in full three-dimensional detail of all components. This process enables you to evaluate and optimize the hot runner and conformal cooling design to achieve an optimal mold design and injection molding process.
With IT manufacturers improving the performance of datacom equipment year after year, the need for accurate design of data centers has become crucial for ensuring safe and efficient design of data centers. Based on the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) publication for case studies on high-density data centers, this class examines some of the most common ventilation strategies employed in existing data centers to understand how to model and set up these data centers for analysis with Autodesk Simulation CFD software and how to validate the results with actual published data. This class will also look at some of the best practices based on the ASHRAE publication and will help designers, engineers, and project managers gain more insight into the design and operation of data centers.
As demand for high performance buildings increases, more sophisticated techniques are needed to ensure a balance between energy efficiency and occupant comfort. Innovative ventilation and energy management approaches require an understanding of airflow patterns and the influence of heat gains or losses. Computational Fluid Dynamics (CFD) enables detailed modeling of these physics yet has historically been too difficult to use early in a project cycle during conceptual design and design development. Over the past 10 years simulation technologies have evolved to become faster, more user-friendly, and more accurate. Autodesk® Simulation CFD 360 is a proven cloud-based tool for examining how air is delivered to and exhausted from a space and the impact of thermal loads. This class will introduce you to CFD workflows and show you how to take full advantage of Simulation CFD 360 for rapid ventilation analysis.
Plant designers face a wide variety of tough-to-solve ventilation and flow control challenges. How can contaminant releases be controlled more effectively? How can you improve energy efficiency? Can you improve flow uniformity through a filter to improve uptime and reduce costs? Designers routinely face these and countless other challenges but until today have had limited ability to examine them in detail. Plant Design Suite subscribers now have access to Autodesk Simulation CFD 360 cloud-based software, which enables designers and engineers to model flow, thermal phenomena, and fluid mixing in complex plant environments. This class will introduce attendees to what Simulation CFD 360 offers and how they can make best use of it for their design work using geometry that was created in AutoCAD® or Autodesk® Revit® software.
Will my part fail? Will it be cooled effectively? Simulation can answer these and other critical questions early in the design process. This class will show how these simulations can be taken a step farther by examining fluid structure interaction (FSI) or, more specifically, taking advantage of the thermal results from a computational fluid dynamics (CFD) analysis to use as input into a mechanical stress and strain calculation. We will examine new workflows for running a thermal analysis in Autodesk® Simulation CFD software, processing the results, and using the thermal data within the setup of a thermal stress analysis.
Compression molding is a process by which pressure is applied to a material by a heat mold. In the case of thermoset elastomers (rubber), the heat and pressure initiate cross linking of the polymer. A specific weight and shape of a material (called a preform) is placed into an open mold, after which the mold halves close. This compression stroke forces the resin to flow and fill out the cavity. After the mold is filled and pressure is applied for a given time (cure time) the mold is split open and the part is removed either by hand or by ejection methods. This process can be applied to both thermoplastic and thermoset materials, both with or without fiber reinforcement. Compression molding simulation can help determine the feasibility and conditions of the manufacturing process, including the size and placement of the preform(s), the internal cavity pressures, and temperatures during the process. These factors enable us to determine how tool and process design affect product quality. During this class, we will discuss an application of compression molding and compare it with compression molding analysis results.
This class will discuss the tools available in Autodesk® Moldflow® Insight for simulating the dynamic temperature changes experienced in the mold during an injection molding process by using the Cool Finite Element Method (FEM) functionality. Topics covered will include modeling requirements, process setup and workflow, theory, result interpretation, and validation examples. Focus will also be given to new functionality available in the Scandium Technology Preview supporting dual-domain part models, thermoset molding and variable coolant inlet temperature processes, including Rapid Heating and Cooling of the Mold (RHCM), also known as Rapid Temperature Cycling or Variotherm. In addition, examples will be shown to demonstrate how to model complex 3D cooling channels (conformal cooling).
