- Today’s presentation is all about the value of virtual simulation and more particularly of CFD to help you and your companies facing business pressures. First, let’s review the most common business pressures companies are facing today. Then, we will investigate together how CFD and SOLIDWORKS Flow Simulation, get product Engineers to understand better the product behavior and then design better products. <Next Slide>
- In any industry, manufacturers have been increasingly challenged to deliver new, high-quality innovative products faster, and at competitive costs. In today’s environment, companies must address many different factors in order to be successful. A key business driver for companies is the innovation: finding the best and the newest products to stay leader in their market or to win new market share is what makes managers awake in the night. CLICK But creating better or more effective products or technologies that are accepted by markets is not that straightforward. Indeed, companies are striving to design innovative products while reducing the cost of product development and time to market. CLICK With these business pressures, manufacturers are looking for business execution’s improvements. To do so, they need to find the right product development process to balance cost and time to market, to come with the best products with fewer mistakes for their customers and prospects. <Next Slide>
- The key challenges that companies face when they want to improve their business execution and their product development process are: The fact that products are becoming increasingly complex. Many products have evolved into complex systems of mechanical components, electronics and software involving multiple engineering disciplines. In addition, the increasing number of components, often combined with miniaturization, requires an even greater understanding of how they will interact, while make sure they do not overheat. CLICK Product performance is also impacted by multiple physical forces. These forces, coupled with the complexity of the products, makes predicting how the product will function in a real world pretty difficult, only by experience. CLICK Undetected mistakes are major sources of cost and time consumed that undermine profits and decrease the windows of opportunity to sell innovative new products. If the mistakes reach the market, the company's reputation and global business could be severely damaged. For example, an engineering change to electronics during a late design stage can be 300 times more expensive to process than if the change is made early in product development. The economic cost is compounded by damage to the brand. These challenges create a need for improved way for assessing products behavior. Standard testing method or the experience are not enough anymore to understand the impact of product changes on performance… <Next Slide>
- Product changes should then be investigated during the design phase for a best quality and lower costs. Engineering is all about making technical decisions to come up with the best design. Engineers, when designing their product, investigate its performance for various physical scenarios and use cases. They assess the product behavior so it fits into the product and market requirement. A 2011 Aberdeen reports lists here the Top Business Pressures driving a Better understanding of Product behavior for companies impacted by fluid flow. Engineers needs to be able to make the right decision with (CLICK) shorten product development schedules to competitively differentiate their products trough quality, cost and innovation. <Next Slide>
- So now, the question is; How Product Engineers can address these business pressures, how can they shorten product development process, how can they design the best products for performance, quality and innovation? CLICK 3D virtual simulation is the engineering tool which helps design engineers in facing these challenges. Gartner, in 2011, underlines that simulation and CAE technologies have proven their ability to increase competitiveness of engineering and manufacturing firms by detecting design mistakes early in new product development, before manufacturers and suppliers have made significant commitments to production Something important to remember is that simulation and CAE not only identify such errors early — while the impact is low, they can also provide insights to better designs and processes, to optimize the product. Simulation provides deeper insights into the quality and safety measures of products and structures, such as performance and reliability CLICK The 2011 market survey conducted by Aberdeen Group I already mentioned provides guidance to help companies in making better designs that will lead to more profitable products. One of the key data is that ‘Product development needs better insight into product behavior to address time, quality and cost pressures’. They found out that business pressures such as Shorten product development schedules Competition Customer demands for lower cost products but at the same quality Drive companies to better understand product behavior during the development process. One of the takeaways is that enabling product development team to make better design decisions with virtual simulation and CFD has a direct impact on the success of the overall company” <Next Slide>
- Analysis is becoming essential for Product Engineers as they need to Perform what-if design scenarios, variations to determine the best performing product Use the proper engineering tools to get the insight they need when investigating technical solutions such as a new material, a new geometry, a new mechanism. This is crucial so they can be assured that their designs are progressing in a valid direction long before there is a complete product design. CLICK Simulation is becoming as essential as 3DCAD for product design and is part of the global design software toolbox. It provides to Product Engineers the results they need to assures that products reach the marketplace without crippling design flaws Meets customer requirement Meets company strategy of quality & performance Answers costs pressure
- In a survey conducted by Aberdeen Group on more than 700 companies that develop products that are impacted by Fluid flow, they asked to companies using CFD, computational fluid dynamics what would be the biggest impact if CFD was not used by Design Engineers. It is all about quality, cost and time savings. For example, a single prototype test might cost $250,000 or more to perform, and requires several weeks or months to set up. Taking into account the cost and time of the original CFD simulation and the subsequent simulations, using the existing model with some modifications, manufacturer could run approximately 15 to 20 simulations for the cost of one physical test. Prototypes are not done on every product and each design variations, limiting the complete understanding of the product behavior. Also, the nature of simulation data provides a more comprehensive view of predicted behavior, since data can be collected and analyzed from anywhere on the model, while data from physical prototypes can be collected only from points where gauges or sensors are mounted. Therefore, when the simulation models are sufficiently comprehensive, engineers can gain quicker insight into the behavior of a design than physical tests. Manufacturer gains the full benefit of CFD by treating it as a means of generating insights and knowledge. Aberdeen reports states that these Best in Class companies have been able to address the top pressure of shortened development schedules and as a results have reduced their development time by an impressive 28 % since implementing CFD for assessing product behavior. They can release products on time. Their up-front work gives them a deeper understanding of the product and key factors that impact performance, saving time later in the development process. You want to be in this Best in class group? Let’s discover now together the CFD offer for SOLIDWORKS users; SOLIDWORKS Flow Simulation <Next Slide>
- SOLIDWORKS Flow Simulation software is a powerful computational fluid dynamics (CFD) tool that enables designers to quickly and easily simulate fluid flow, heat transfer, and fluid forces that are critical to the success of the design. CLICK SOLIDWORKS Flow Simulation is fully integrated within SOLIDWORKS 3D CAD software, so you can use all the benefits of a fluid flow simulation to design your products with better insight. Design variations can be compared to make better decisions, resulting in products with superior performance. You can, for example, simulate the water flow inside a valve to dimension it (pressure drop, velocity, turbulences), test the air flow inside an electronic enclosure to optimize the cooling process, or check the air flow around vehicles, among a broad range of applications. CLICK Concurrent engineering helps detect design flaws early in the design cycle, and helps compare design scenarios before going further in the design process. CLICK With SOLIDWORKS Flow Simulation and the wide range of technical capabilities that you can see on the slide, you can gain an understanding of the impact of flow on the design before it’s built. <Next Slide>
- What are the typical Engineering challenges answered with CFD? Pressure drop is a term used to describe the decrease in pressure from one point in a pipe or tube to another point downstream. This parameter is a standard result that CFD engineers are looking for. For example, the objective of a duct design is to size the duct so as to minimize the pressure drop through the duct, while keeping the size (and cost) of the ductwork to a minimum. SOLIDWORKS Flow Simulation helps designers to investigate and optimize pressure distribution in a wide variety of products such as valves, nozzles, controls devices… CLICK Flow Fields When you are designing a product in which or around which fluid is flowing, it is important to understand the fluid flow behavior ; fluid velocity, fluid trajectories, turbulences risk… With SW Flow Simulation, you can inspect and optimize complex flows in and around objects with internal and external analysis. CLICK Heat Transfer Heat transfers throughout our environment all the time. Wherever you are, you are aware of things that are warm or cool or are getting warmer or cooler… This is a very common challenge in electronic devices. Indeed, they have less and less space to provide airflow as they are smaller and smaller so it is an ongoing thing that needs to be prevented in order to keep the equipment in good health… With SOLIDWORKS Flow Simulation, you can simulate fluid flow as well as coupling it with heat transfer such as convection, conduction or radiation… Designers can apply heats sources, thermal properties on components, define fan position for example and the get as a results the temperature distribution both for the fluid and the product itself. CLICK Force Prediction Several products are impacted by fluid flow; their mechanical resistance , their performance can be affected by the related fluid forces. When air is flowing around a radar tower, it is important to understand the turbulence around the tower and the forces applied on the structure for a complete performance test. SOLIDWORKS Flow Simulation helps designers to inspect related forces on immersed or surrounding components. Moreover, to close the loop, you can export the fluid flow results such as pressure and temperature to SW Simulation for thermal and thermal stress simulation. These are typical applications but SOLIDWORKS Flow Simulation is appropriate for many more application. <Next Slide>
- To summarize this session, As product complexity continues to increase, CFD will need to be used by a broader range of Product Engineers in any industry Performing CFD simulation is key to ensuring that products perform as required. CFD with SOLIDWORKS Flow Simulation can be used earlier and frequently in the product development cycle to get the full benefits of concurrent engineering; Quality, Cost and Time savings. <Next Slide>
