Maxwell Time Decomposition Method Accelerates Simulation of Transient Electromagnetic Fields with Intel Xeon Processor E5-2697 v4 - White Paper

ANSYS teamed with INTEL to benchmark a new ANSYS Maxwell technology that delivers dramatic speed improvement for transient electromagnetic field simulations. Simulations that previously required weeks of computation time are now completed in a matter of hours. The key software technology is a new algorithm within Maxwell that allows engineers to solve time steps simultaneously as opposed to sequentially.

ANSYS CFD Provides the Best of Both Worlds: Most Accurate Results and Fast Prep and Meshing - White Paper

Fidelity and accuracy are critical in computational fluid dynamics (CFD) simulation. After all, physical prototyping and testing can only be reduced if one can expect accurate simulation results. But up to now, high fidelity, high accuracy results have come with a price. Complex, realistic geometries have required hours of manual effort to clean up the model and prepare the mesh. Users have been tempted to cut corners and take shortcuts that speed up prep but take a toll on accuracy and fidelity. There is no way of knowing just how those inaccuracies skew results, putting any recommendations in doubt. For example, if you don’t resolve a boundary layer correctly then any aerodynamic drag figures could be highly inaccurate.

Overcoming Thermal Management Challenges with Multiphysics Simulation - White Paper

Designing products, components and systems that can withstand a wide range of thermal scenarios is a design challenge that touches nearly every industry. From automobiles to high-speed semiconductors, thermal management concerns can often lead to wasted energy, reduced performance or premature device failure. This results in increased energy costs, warranty issues and additional design time that can reduce competitive advantage. To master thermal management design and truly understand thermal behavior of a system, streamlined multiphysics simulation tools are a necessity.

Shape Optimization for Aerodynamic Efficiency using Adjoint Methods - White Paper

Adjoint solvers take a Computational Fluid Dynamics (CFD) flow solution and calculate the sensitivity of performance indicators (e.g. drag, heat transfer) to all of the design variables. Once an adjoint solution is obtained, the designer has key information on how to alter the shape of the design in order to improve the quantity of interest. Mesh morphing is an easy and powerful tool that allows the geometry to be altered at the mesh level and within the parallel solver in order to evaluate effects of the design alterations. The user may then iterate on this process to achieve an optimum design without the need to return to the original CAD geometry. For complex geometries, the aerodynamic interactions become complex and the insight gained by such an optimization method can take the design in directions which would not be intuitive to follow and difficult to represent using parametric geometry.

Why Engineering Simulation is Critical for Breakthrough Energy Innovation - White Paper

Breakthrough Energy Innovation requires ambition and urgency. Developments will come in the areas of renewable energy production and improving energy efficiency in the industrial and transportation sectors. However, many products in these sectors are already highly tuned for their function. Consequently, higher fidelity understanding of product behavior is required to identify additional incremental improvements. For more disruptive innovation, a very wide design trade space becomes necessary as products are often more complex, do not have a history of operational experience, and function in different environments that include design variables outside of the traditional product’s boundaries. To address these challenges, companies are turning to simulation. It’s a solution that allows designers to get deeper insight into product performance and consider hundreds, if not thousands, of design iterations.

Verifying and Validating Software in a Regulated Environment - White Paper

The ANSYS, Inc. Quality System is set up to meet the requirements of the International Organization for Standardization (ISO) ISO 9001:2008 as well as the applicable requirements of the U.S. Nuclear Regulatory Commission’s, Rules and Regulations in Title 10, Chapter 1, Code of Federal Regulations, Appendix B to 10 CFR Part 50, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants” and Title 10, Chapter 1, Code of Federal Regulations, Part 21, titled "Reporting of Defects and Noncompliances" for reporting and dedication of commercial grade items. For customers who perform analyses for nuclear application, a quality assurance service was developed in the 1970’s which affords customers the ability to purchase software that meets the requirements of the U.S. Nuclear Regulatory Commission (NRC). We use the American Society of Mechanical Engineers (ASME) NQA-1 Standard to accomplish this.

Dedication of Commercial Grade Design and Analysis Software - White Paper

"Until recently, quality processes known as software verification and validation were typically used as qualification of commercial grade software in many software quality assurance programs. Many believed that commercial grade dedication was not an option for complex items such as computer programs. Although discussed in terms of plant structures, systems, and components in 10CFR21, the Nuclear Regulatory Commission (NRC) concluded that design and analysis software could meet the definition of a commercial grade item in the U.S. NRC Safety Evaluation Report (SER) of Topical Report.

In this report, the NRC noted that existing software quality assurance practices that rely on verification and validation alone may not be sufficient to accept commercial grade computer programs for use in safety-related applications. The NRC emphasized that commercially produced computer programs used for safety-related design and analysis are considered to be safety-related, and safety-related items must be either designed and manufactured in accordance with a quality assurance program that meets the requirements of Appendix B to 10CFR50, or dedicated for use in a safety-related"
