It is extremely important for manufacturing industries to reduce their design process period in order to keep a competitive position in worldwide markets. CAE has been and will have an even more important role in shortening the design process. To effectively use CAE as a part of the design process, the ability of doing analysis in an affordable way, using large-scale real life problems is commo...

Performing a finite element analysis (FEA) on a hyperelastic material is difficult due to nonlinearity, large deformation, and material instability. This paper provides a brief review of the hyperelastic theory and discusses several important issues that should be addressed when using ANSYS. Analysis on a fatigue specimen is used as an example of one of our product development challenges upon w...

There is an ongoing interest in analyzing the flow characteristics of swimming fish. Biology has resulted in some very efficient motions and formulating these motions is of interest to engineers. One such motion theory was written previously by Vorus and Taravella, and the University of New Orleans was given funds by the Office and Naval Research to test this theory. Computational fluid dynamic...

18 ANSYS ADVANTAGE ISSUE 2 | 2017 Leading the Electric Vehicle Charge The battery management system plays a critical role in today’s electric vehicles: It monitors the state of the battery, manages its operation to optimize vehicle performance and battery life, and ensures the safety of occupants. Researchers at National Electric Vehicles Sweden (NEVS) who are developing the BMS for their next-...

Traditionally the resistance of ships has been determined using towing tank experiments. Over the past two decades increased computational power has allowed numerical approaches to replicate and potentially start to replace towing tank experiments. This work investigates the quality of results that can be achieved using a commercial Reynolds Averaged Navier Stokes (RANS) flow solver, ANSYS CFX ...

A one-step, a two-step, an abridged, a skeletal and four detailed kinetic schemes of hydrogen oxidation have been tested. A new skeletal kinetic scheme of hydrogen oxidation has been developed. The CFD calculations were carried out using ANSYS CFX software. Ignition delay times and speeds of flames were derived from the computational results. The computational data obtained using ANSYS CFX and ...
