Perform multiphysics CFD simulations that are within 2% of physical experimental results

To simulate fluids or gasses, you might use CFD. To simulate solids, you might use FEA or MBD. To simulate the real world, such as a wind turbine moving through the air, a pure CFD or a separate pure FEA analysis is sometimes not enough. Instead, a multiphysics simulation, or co-simulation, is necessary to ensure …


MSC Nastran 2019.0: Improved Accuracy Without Sacrificing Performance Speed

Join us to learn more about the exciting new capabilities available in MSC Nastran 2019.0, available in January, 2019. With the advances in electric car manufacturing, and quieter electric motor engines, high frequency Noises and Vibrations are becoming more prominent, which makes NVH calculations exponentially more expensive. In this release, we are introducing a new …


Analysis of IXV Space Hardware Exposed to Acoustic Diffuse Random Field

Reusable launchers are recognized as one of the solutions to lower launch costs. Contrary to more traditional expendable launchers, the reusable launchers are able to launch a payload and return part of the structure on the Earth surface. In 2015, ESA launched the Intermediate eXperimental Vehicle (IXV). This vehicle was developed by Thales Alenia Space …


Noise Prediction for Electric Vehicle Powertrain

NVH (Noise, Vibration, and Harshness) or N&V (Noise and Vibration), is a problem that is often directly tied to the overall quality of a product. Therefore, it is one of the most sought after targets for performance by product development teams to help differentiate themselves from competition. With the emergence of hybrid and electric vehicles, …


Industry Applications of NEVF with Dr. Neil Bishop

Dr. Neil Bishop of CAEfatigue Limited, one of the most renowned experts in Fatigue Dynamics and FEA, partnered with the MSC Nastran team to create a more dynamic and integrated solution after experiencing the many limitations of fatigue simulation. Thus, Nastran Embedded Vibration Fatigue (NEVF) was born. NEVF is more accessible, easy-to-use, and flexible in …


Accurately Predicting the Behavior of Pneumatic Tires

When developing the sub-systems of a vehicle, compromises have to be made among several contrasting objectives. On one hand, one wants to set all sub-systems – such as suspensions – so that they allow efficient and safe handling of the vehicle. On the other hand, comfort cannot be sacrificed too much. Being the support of the vehicle and providing forces necessary to control it, pneumatic tires are one of the most important components. However, it is very challenging to model them due to both their complicated composition and the materials used in their manufacturing process. On top of that, the modeling is done by suppliers and an in depth understanding of the interaction with the vehicle must be attained.
