Mesh Technologies for CFD - Pros & Cons
Requires Flash Player.
Cleaning up CAD geometry to create a surface mesh, creating and finally smoothing the volume mesh can be the most time consuming steps in the entire simulation process. The final mesh quality also has an impact on the solution time, achievable level of convergence and resulting solution quality. The presentation will start by recapping the need for a computational mesh, and reviewing the basic choices available. Factors affecting the choice of grid system such as cell shape, geometry representation, mesh structure and grid generation will be discussed in turn.
Duration: 48:45
Products: FloEFD™

Overview
This web seminar discusses one of the most important yet vexing topics in CFD – meshing. Cleaning up CAD geometry to create a surface mesh, creating and finally smoothing the volume mesh can be the most time consuming steps in the entire simulation process. The final mesh quality also has an impact on the solution time, achievable level of convergence and resulting solution quality.
The seminar recaps the need for a computational mesh and reviews the basic choices available. Factors affecting the choice of grid system such as cell shape, geometry representation, mesh structure, and grid generation are discussed in turn. A number of examples are presented, finishing with an overview of Rectangular Adaptive Meshing.
DURATION: 48 minutes
What You Will Learn
- The need for a computational mesh in CFD
- The choices of grid system and their pros and cons
- How mesh quality affects result quality and convergence
- Recent developments in meshing technology
