"A decisive advantage offered by MEMS technologies is the possibility of implementing sensors and actuators within arrays. This requires knowledge of the different physics each section of the device requires, for it to work. Using ANSYS Multiphysics enables us to couple these physics and accurately predict there performance."
- Patrice Minotti, Chairman, SilMach, CNRS Research Director
"Over the past six years FLUENT has been our Computational Fluid Dynamics (CFD) tool of choice within the Print Engine Development Unit at Xerox Corporation. We use the code to solve a wide variety of fluid dynamics and heat transfer problems both at the sub-system and system levels. The robustness of FLUENT CFD allows us to develop concepts into final designs with minimal testing and building of prototypes. It is estimated that the cost savings in reducing prototypes and testing alone are a significant percentage of the overall development costs. More important, however, is that FLUENT also provides an in-depth understanding of sub-system interactions within the print engine architecture. These interactions are difficult, and in many cases, impossible to measure using lab equipment."
- Francesco Zirilli, Ph.D., Principal Engineer, Print Engine Development Unit, Xerox Corporation
"Certain key generator characteristics; the subtransient reactance, the open-circuit saturation curve, and the output voltage signal harmonic distortion can be difficult to predict and are typically determined from physical testing. Using ANSYS Emag enables us to determine these key generator characteristics and accurately predict generator performance before creating a physical prototype."

"Thank you very much for a job well done. We appreciate your help on this difficult problem and are very happy with the results. The speed and thoroughness of your thermal analysis and modeling work is really commendable. We look forward to working with you again in the future. For many years, we have been prototyping and re-prototyping to pass our vigorous thermal requirement. Lots of money and time have been lost but worst was the big delay in our schedule. Today, with the use of Icepak, we are able to optimize the design during the conceptual design phase. When we tested our first prototype, the difference between the measured data with the Icepak result was .5°C for the 250A design, and .95°C for the 600A design. In addition, the simulated scenarios show that the units will pass the 150% overload at an altitude of 2000m. This is a big step to shorten our design and development time and to deliver a reliable and cost effective product. I am very pleased with the accuracy obtained and am grateful for the prompt support from all highly professional and very competent application engineers."

"The development center of Bühler Motor in Nürnberg uses 3-D CAD and FE tools in the virtual design process of DC and gear motors. For more than 10 years, we have systematically analyzed and optimized different components of our products with the FE analysis programs from ANSYS."

"We had a very short time to resolve the thermal issues in our new Optical Network Terminal. We needed help and asked Fluent to assist us with the thermal design and simulation of this product. Fluent engineers very quickly built detailed CFD models and solved them. After prototypes were made, we measured the temperature rise in the optical circuit and were astonished to see that it was only 0.6C at high altitude! This was well within the very challenging target of 1C rise over ambient temperature. Fluent engineers did this on time and accurately; the results were beyond our expectations. I highly recommend Fluent Thermal Consultants for any challenging thermal design and analysis work."
- Mohammed Tahmaspur, Director of Product Design, Terawave Communications
"The ability of ANSYS to work well with ESAComp, to provide a robust parametric model representing all the different components and to reliably perform both structural and thermal analyses was key to the speed and accuracy in successfully completing the ESA study. With the help of this level of advanced analysis, the behavior of the structure could be properly understood, the design of the composite housing was optimized to provide a mass saving of 29 percent over a comparable aluminum housing, and the project was completed in only 18 months from the kick-off meeting to the final presentation of results."
- Harri Katajisto, R&D Engineer, Componeering
"We chose Icepak over other electronics cooling software for its ease-of-use and several advanced features. The universities and telecommunication companies we work with tell us that Icepak is the appropriate software to use in the field of electronics cooling. This was also very important to us. In addition, we can get access to advanced models in FLUENT, if and when needed. Icepak contains several features that benefit our needs, including the ability to handle circular, cylindrical, elliptical, and polygonal objects, both in 3D and 2D, allowing us to handle details like heatsink fins with aerodynamic design. Icepak is also faster due to the smaller meshes that follow the complex geometry. Further, the non-conformal (assembly) meshing creates models with fewer cells, retaining the degree of accuracy. Icepak also offers a "Zoom-In Model", helping us to analyze a selected region of a full-sized model in greater detail by automatically creating the zoomed-in model with boundary conditions from the full-size model."

"ANSYS DesignSpace is an ideal tool in early product development for conceptual simulation-based design and was instrumental in the success of developing the iGen3 digital printing system. Also, full ANSYS is one of our primary analysis tools for advanced simulation, particularly in multiphysics applications where multiple physical factors must be evaluated. In typical product development programs at Xerox, simulation-based methods using these types of predictive tools have definitely helped reduce the number of prototype testing iterations, each costing tens of thousands of dollars and weeks of time. In the end, development time and costs are reduced. But more significantly, our high quality standards are met and time to market is shortened in developing innovative winning new products such as the iGen3, enabling Xerox to grow top-line revenue and increase market share."

"We, at Philips Lighting, use ANSYS Multiphysics for the design optimization of high pressure Ceramic gas Discharge Metal-halide lamps. The model of the CDM-lamp Consists of different physics (heat, fluid and mechanics). ANSYS Multiphysics makes it possible to simulate the CDM-lamp in one single model. We succeeded to model the gas discharge, which is very nonlinear with respect to the heat generated in it. We can run several tests in a single day and gain a thorough understanding of the design performance."

"Designing ahead of the market allows us the processing and tooling lead times that we need. ANSYS helps us with competitiveness by identifying long-lead time items and indicating factors that might lower manufacturing yields. ANSYS also helps us avoid the time and cost of having to make physical prototypes."

"ABB engineers continuously strive to improve product efficiency, but some heat losses are inevitably present, from small light dimmers to large converters. Since product performance and reliability are ABB's primary targets, it is vital to have an excellent thermal design. Low temperatures and low temperature gradients are the keys for higher reliability. A more efficient thermal management also allows more power to be drawn by the same device, thus stretching its range of operation. Icepak software provides a quick, accurate and reliable tool for the thermal management design and analysis of our products."
- Dr. Matteo Fabbri, Scientist, Corporate Research, ABB Switzerland Ltd.
"We routinely depend on FLUENT CFD software to select and optimize designs well before prototypes are built. In alleviating the need for iterative hardware builds, this streamlines the design process and thus, significantly reduces development costs and minimizes time-to-market."

"FLUENT is a very effective tool in our design-by-analysis process. The use of FLUENT software has improved our understanding of complex flow and heat transfer in our products, which would otherwise be difficult to determine and visualize. This insight minimizes our use of costly experimental prototypes. In a recent project, we easily saved over $10,000 in redesign costs by using FLUENT in the design process."
- Bill Edwards, Staff Engineer, BTU International
