Setting up boundary conditions is one of the critical components of any CFD simulation, and the use of appropriate boundary conditions is essential to the accuracy of the CFD solution. In this video, you will learn how to set up boundary conditions using the Boundaries menu under the Zones group in the Physics tab of Ansys Fluent. You will learn how to access the boundary conditions panel, how to specify and copy boundary conditions, change boundary type, and specify boundary values using Expressions and the Quick Property Editor panel. You will explore the Multi Edit feature and the different ways of transferring boundary conditions from one Ansys Fluent case to another. You will also learn the importance of defining well-posed boundary conditions and the recommended combinations.
