How To Mesh - A CFD Meshing Demonstration Series Part 1

Accuracy of simulations to a large extent depends on type of mesh and mesh quality. Preprocessing can form major part of the man hours in simulation, if best practices and meshing strategy to generate quick and high quality mesh are not followed.

This series of Ask The Expert on CFD Preprocessing is intended to help users in better understanding and implementing efficient meshing strategies and parametric modeling. The sessions will predominantly have demonstrations. In the series, meshing workflows, meshing strategies for applications and productivity improvement tips will be demonstrated through several case studies. In addition, the advantages & usage of usability features which improves user’s efficiency and speed will be discussed. The selected case studies include key applications from oil & gas/process/automotive and turbo industries.

Part 1: How create Gambit like Hex/Hybrid Meshes in ANSYS Mesher and use parametric modeling in ANSYS WB to replace Gambit Scripts?

Are you still missing on taking full advantage of ANSYS Workbench Workflow because you are not sure how to get Gambit like meshes in WB or how to migrate Gambit scripts? Or you have started using DM and ANSYS WB, but feel lost as it is very different from Gambit. If you often have questions like, this webinar will help in providing you guidance. This session will demonstrate hex meshing creation and parametric modeling in Workbench.

Case Study

ANSYS Helps AGCO to Reduce Development Times and Maintain Global Leadership

Tractors, harvesters and other agricultural equipment are used in rough terrain and under tough conditions. Immense forces are created when the heavy equipment is in operation. Engineers at AGCO must evaluate loading conditions from day-to-day equipment operation and from use outside of normal operations. Engineers at AGCO use ANSYS structural mechanics software and ANSYS Workbench to reduce development time and allow engineers to focus more on engineering their products.

Diagnosing Nonlinear Structural Solutions in ANSYS Mechanical

Linear, elastic, static structural analysis has always been the most common structural analysis methodology. However, as the need for higher fidelity simulations continues to grow, nonlinear structural solutions are becoming increasingly more common. Nonlinear structural behavior is caused by strains exceeding the material’s elastic limit, deformations changing the structural stiffness, and/or changing contact status. All of these nonlinearities add to the complexity of the solution. ANSYS Mechanical 14.5 contains a robust set of nonlinear diagnostic tools applicable to each of the nonlinear behaviors.

This webinar will explain the available tools for diagnosing nonlinear structural behavior in ANSYS Mechanical R14.5. The webinar begin with a presentation and live demo.

Designing a Flapping Wing Type Micro Aerial Vehicle Using ANSYS

Presented by Taher Basrai from the Georgia Institute of Technology, ANSYS was used to design parts of a robot dragonfly like vehicle. The lift and trust characteristics of flapping wings are major factors affecting performance and power requirement for a Micro Aerial Vehicle (MAV). ANSYS Fluent proved to be instrumental to obtain the flow characteristics and lift and drag force data on flapping wings.

To provide additional DOF for wing feathering, an innovative dynamic mesh UDF was developed by students of the Georgia Institute of Technology to handle change in velocity references from local to global co-ordinates in Fluent. Various cases made of combination of variables that affected flapping wing performance like amplitudes, flapping frequencies, wing shapes and materials were run seamlessly in Fluent. Through use of batch files in Fluent the parameter sweeps could be automated. Powerful post-processing tools available with ANSYS made it possible to vividly visualize complex fluid flow around flapping wing. The ability to simulate through ANSYS effectively narrowed the scope of experimentation and as a result the prototype development cycle time was significantly reduced. The innovative wing design is currently used in flapping wing system of Micro Bio-Aerial Robots at companies like TechJect Inc.

Total Brake System Design and Instability and Noise Prediction

Automotive and Aerospace braking systems can generate several kinds of noises. Brake discs develop large and sustained friction-induced oscillations, referred to simply as brake squeal. Many engineering approaches have been implemented to attack the problem. One example is the complex eigenvalue method by which squeal propensity is quantified by the dynamic instability of a certain system mode. In ANSYS, to predict the onset of instability, one can perform a modal analysis of the pre-stressed structure. The pre-stress may be due to a combination of assembly/operational loads and thermal loads. The presence of unstable modes suggests that the geometry parameters and material properties of the braking system need to be modified.

ANSYS offers three different methods to perform a brake squeal analysis. These three methodologies can be executed in a parametric and persistent environment called ANSYS Workbench. A parametric workflow, from CAD model to CAE solution, is in turn the path to parametric design optimization.
