Computational Fluid Dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to solve problems involving fluid flows. The Computational Fluid Dynamics (CFD) Training provided by Multisoft Systems is designed to enable the product design team to optimize their engineering design and reduce their risks of potential design failures. Hence, it helps both individuals and companies in getting a competitive advantage in the current marketplace. The participants are supposed to obtain their own licensed copies of ANSYS Fluent® (it should be ideal to be installed on most MS Windows 64-bit machines) or download a new and free student version of the software license from ANSYS.
Our offered Computational Fluid Dynamics (CFD) Training will help you in setting up the most appropriate CFD model concerning material properties, boundary conditions, solution monitor, and solution control parameters. It is also designed to help you in extracting the required results and plots from the wealth of information available at the solution stage.
- How to configure the most appropriate CFD model for the problem at hand?
- How to configure the most appropriate turbulence model for particular applications?
- How to conduct both steady-state and time-dependent fluid flow simulations?
- How to resolve for both isothermal and non-isothermal thermo-fluid
- applications by including all the necessary modes of heat transfer
- How to resolve for both Incompressible and Compressible fluid flow applications
- How to resolve for fluid flow through porous media and rotating machinery
- How to extract the required results and plots from the wealth of information available at the solution stage?
- The Computational Fluid Dynamics (CFD) Training is mainly designed for the ANSYS Fluent® users, but it can also be pursued by the designers, engineers, scientists, and managers interested in gaining an insight into this technology and some of its vast range of capabilities.
- A participant of Computational Fluid Dynamics (CFD) Training needs to download a new and free student version of the software license from ANSYS or obtain his/her own licensed copies of ANSYS Fluent®. This software license should be ideal for installing on most MS Windows 64-bit machines.
