Description

The first part of the course will deal with the manipulation of CAD geometries to prepare the model for the subsequent CAE phase. It will then cover domain decomposition in order to use the best meshing methodology, evaluation of the relevance of geometric details to the analysis, and handling named selections and parameters.

Next, the basic concepts for generating the computational grid for a CFD analysis will be explained. The methods of generating the computational grid will be presented starting with the global control parameters and then delving into local infill methods. Special emphasis will be given to the construction of prismatic wall layers, a relevant aspect for CFD simulations.

Finally, the course will provide a comprehensive overview of how to set up and solve a thermo-fluid dynamic analysis. The basic steps for setting up the physics of the problem from importing the computational grid to launching the numerical solution will be described. These include: selecting the best-fit model for the simulated physics, assigning fluid properties to computational domains, entering boundary conditions, setting up the numerical solver, and choosing initialization methods. More vertical topics such as turbulence modeling, transient analysis, and heat transfer modeling (conductive and convective) will then be introduced. Through application examples, methods for evaluate the correctness of the simulation (checking quantities of interest using monitors and reports) will be explained.

The course participant will be guided in learning through hands-on "hands-on" sessions that will allow for verification of understanding of the topics presented.

Target Audience

The course is intended for engineers and designers who intend to perform thermo-fluid dynamic simulations as part of product design and/or optimization.

Pre-requisites

The course is usable by all with no special pre-requisites. Basic knowledge of fluid mechanics and heat transfer is recommended.
