Add Boundary Layers

Boundary layers are thin, viscosity-dominant regions that form along the surface of a solid body as a fluid flows past it. These regions play a significant role in defining the overall fluid dynamics of the problem, and consequently require special attention while simulating the fluid flow for such problems using computational fluid dynamics (CFD). In this course, the focus is on understanding the Add Boundary Layer task of the Ansys Fluent Meshing Watertight Geometry Workflow, which is used to create high-resolution meshes that can capture boundary layer flow physics. This course consists of three videos and will take you through various aspects of boundary layer mesh generation. In the first video, we will look at the importance of boundary layer mesh and learn the user inputs required in this task. Next, we will learn the details about boundary layer mesh generation methods, along with a discussion on their advantages and disadvantages. Finally, we will learn how to specify the regions and surfaces of interest where the boundary layer mesh needs to be defined.

A course completion badge allows you to showcase your success. We partner with the Credly Acclaim platform, and digital badges can be used in email signatures, digital resumes and social media sites. The digital image contains verified metadata that describes your participation in our course and the topics and skills that were covered. This badge is for successfully completing the Add Boundary Layers course.
