- Today’s presentation is all about the benefits of Computational Fluid Dynamics (or CFD) for Product Engineers. Fluid and heat flows and transmit in a wide variety of products from valves, medical device with blood flow, electronic components and much more. For these products submitted to gas or liquid flow, the understanding of this flow and the often the transferred heat is crucial for a proper product dimensioning and an accurate answer to the technical requests. But, historically, Computational Fluid Dynamics Simulation has only been used by very few product engineers, mainly by CFD specialist for product validation only. CLICK The objective of this presentation is to present you in 22 minutes a unique CFD engineering tool, SOLIDWORKSFlow Simulation, made by engineers for Product Engineers. We will discover today why SOLIDWORKSFlow Simulation is the unique SOLIDWORKSembedded CFD simulation tool which enable all SOLIDWORKSuser to get the technical insight they need while designing their products and not only at the end of the Product Development cycle. Let’s get started. <Next Slide>
- It is now pretty well known in the engineering community that Simulation and Analysis is becoming essential for Product Engineers as they need to Perform what-if design scenarios, variations to determine the best performing product while they design it. 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 important 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 3D CAD 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 issues Company can then meet customer requirement Product Development team can meet company strategy of quality & performance And globally the manufacturing company is able to answer time and costs pressure What’s about the benefits of CFD more specifically? <Next Slide>
- A 2011 market survey has been conducted by Aberdeen Group on more than 700 companies that develop products that are impacted by Fluid flow. The goal was to provide guidance to help companies to make 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’ and that CFD has a direct impact on the success of the overall company” CLICK Then, Aberdeen group asked to these 700 companies using CFD what would be the biggest impact if CFD was not used by Design Engineers. It is all about quality, cost and time savings. They underlined that ‘yes my product would work but it would not be optimized for cost, quality and performance…’ This impact is vey important. I am pretty sure that your products are working, they deliver the functions they are supposed to deliver. But are they optimized, are they innovative? Such companies have then been able as well to reduce significantly prototyping cost and time. This report highlights that manufacturer gains the full benefit of CFD by treating it as a means of generating insights and knowledge such as A reduction of 28 % of development time An impressive improvement of product quality With the benefits in mind, it is now time to discover together the unique CFD offer for SOLIDWORKSusers; SOLIDWORKSFlow Simulation. <Next Slide>
- SOLIDWORKSFlow 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 SOLIDWORKSFlow Simulation is fully integrated within SOLIDWORKS3D 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 SOLIDWORKSFlow 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>
- SOLIDWORKSFlow Simulation is a unique Computational Fluid Dynamics (CFD) software based on Engineering goals and technology. CLICK SolidWorks® Flow Simulation is based on the same mathematical foundation as traditional computational fluid dynamics (CFD) software, but key benefits set SOLIDWORKSFlow Simulation apart, making it quicker and easier to use, while still delivering a robust and highly accurate solution. Unique embedded technology makes Flow Simulation the right CFD tool for Product Engineers. Let’s discover them now.
- The background, the foundation of any CFD software is pretty similar…They solves the Navier stokes equations. But to bring CFD analysis into the Product development process and not to limit its benefits to only final validation by CFD specialists, the CFD tool has to be intuitive, engineering driven as well as able to tackle complex CFD studies accurately. This is what SOLIDWORKSFlow Simulation is all about. CLICK (video)
- Ease of use is nothing is your engineering tool is not powerful and accurate. SOLIDWORKSFlow Simulation offers a complete set of CFD functionalities to answer your simulation needs. You are able to simulate (CLICK) internal, external (CLICK) or mixed fluid flow, to couple the fluid flow with heat transfer (CLICK) taking into account conduction, convection and radiation. Fluids can be liquid or gas in your system. (CLICK) Powerful post processing tools allow users to get quickly the CFD results they need to understand how the fluid is flowing, how the thermal energy is dissipating, if recirculation occur in the medical device and so on. The CFD results such as Pressure & temperature can be as well used in a Structural analysis in SW Simulation for a thermal-stress or performance testing on your product. CLICK This makes SOLIDWORKSFlow Simulation the CFD product for Product Engineers. Let’s move on to the second point.
- As I already mentioned, SOLIDWORKSFlow Simulation is fully embedded inside SOLIDWORKS3D CAD. There are benefit beyond the ease of use. Indeed, this enables users to use existing CAD geometry for the CFD analysis, without the need to create extra fluid volume or to translate CAD model. We can then remove the translation process and fluid domain creation challenges which has a direct impact on the user productivity and the capability to integrate CFD into the Product Development Process. Recently a company testing a traditional tool popular in the aerospace industry reported a difference of two weeks compared to two days with SOLIDWORKSFlow Simulation technology. They reported that they spent a majority of their two weeks trying to get their geometry into their current traditional CFD tool. But the same complex geometry was transferred into SOLIDWORKSFlow Simulation and analyzed in under two days—a significant savings. CLICK SOLIDWORKSFlow Simulation uses native SOLIDWORKS3D CAD data and the SOLIDWORKSconfigurations directly and so the fluid domain is automatically created based on the geometry and then is automatically updated for any design changes. This is key for real concurrent engineering, meaning doing simulation early in the design process. CLICK The CFD set up conditions are defined directly on the SOLIDWORKSCAD model. As a result, for any design change, the fluid domain and the CFD boundary conditions are updating for you, saving you preparation time.
- This tight integration of CFD into 3D CAD means that few if not any additional steps are required on the geometry for the CFD analysis. We already mentioned the fact that the fluid domain is automatically created based on the geometry, even if this geometry is complex. This is extremely valuable as you do not need to try to create a cavity inside your products with complex and time consuming CAD features that might not be correct anymore if design changes. In addition, tools such as the leak tracker identify potential geometry issues such as small gaps of holes which might prevent SW Flow to close the internal fluid space. CLICK Moreover, if you have inside your model internal spaces that are not involved in the flow analysis, SOLIDWORKSFlow Simulation can simply exclude them from the CFD model to optimize mesh size and computational time. CLICK Next, the post processing is intuitive and uses existing CAD entities for results display and listing. For example, you can display pressure or velocity distributions on section plot defined on SOLIDWORKSplan. You can track the variation of a parameter such as a temperature in the fluid along a SOLIDWORKSsketch. You can as well display CFD results on the surfaces of the CAD model. This allows users to quickly access to the CFD results they need for their technical decisions.
- Accuracy of a simulation is tightly linked to the quality of the mesh. This is perhaps one of the most important steps in an analysis process and in traditional CFD tools a time consuming and painful process. Indeed while automatic meshers have long been available, traditional CFD tools still require a considerable amount of manual intervention in order to maintain the quality of the mesh. Often, this manual process has to be repeated for every design change. CLICK SOLIDWORKSFlow Simulation offers you an extremely robust automatic mesher for fluid and solid regions with automatic mesh refinement/unrefinement due to geometrical or physical requirements trough a solution adaptative technology. The result is that new parts and design changes can be meshed in a matter of minutes, dramatically reducing the time required for analysis while maintaining the accuracy of the CFD simulation.
- When designing your product, do you know in advance how the fluid will flow inside or around it. Do you know if the flow will be turbulent or simply laminar? Is your fluid compressible? Do you know well in advance the critical areas that might need a finer mesh for a better accuracy? Often, no, we do not know. The good news is that with SOLIDWORKSFlow Simulation you do not need to choose between turbulent or laminar flow as its modified wall function supports a laminar-turbulent transition model. In addition, SOLIDWORKSFlow Simulation will account for compressibility automatically. (CLICK) The solution adaptive meshing, mentioned earlier, will refine the mesh according to gradient in the CFD results so you get accurate technical insight without reading a crystal ball before your CFD set up.
- The value of embedded simulation tools is to be part of the product development cycle. Meaning product engineers can compare designs and find out the best design. Indeed, the design process is an iterative process: after seeing the initial CFD analysis results, most users modify their models repeatedly in order to solve problems or to boost the product performance to their objective. When your 3D design and analysis platform is integrated, as in the case of SOLIDWORKSFlow Simulation with SolidWorks, after your initial run, you simply create multiple clones of your model. The cloned models retain ALL analysis data such as loads and boundary conditions. So when you modify your solid model, you can immediately analyze it without having to re-prepare it. It really is that simple. With other programs you may need to go back to the original CAD model. And while you may be able to use the CAD cloning feature, after the translation process, you still need to reapply all your loads and boundary conditions. This becomes a real hassle if you want to analyze several versions of your model. CLICK (Video) The parametric study enables users to compare automatically design scenarios, with boundary conditions variations, SW dimensions changes and their impact of one of their key CFD results such as pressure drop, force on this piston.. CLICK (Video) The Compare tool, in this video, enables you to compare the CFD configurations in just 1 click and visualize the variation of CFD results such as pressure, temperature or velocity for all the designs scenarios, either in 3D display, either in graph.. All these tools have been developed so you can run powerful What’ If Analysis while you design. Next slide
