Generic Aircraft Geometry – Lesson 4

For simulating external aerodynamics problems such as flow over an aircraft or flow over an automobile, it is critical to ensure that appropriate mesh refinement is used in regions where the flow behavior is highly dynamic — for example, in the boundary layer region or the wake region behind the body. In this workshop, by using a generic aircraft model, we will explore how to use the Ansys Fluent Meshing watertight geometry workflow to create a CFD-ready mesh, with the intention of performing an external aerodynamics type analysis of this model. Specifically, we will discuss how to create local mesh refinement regions by offsetting the surface of the model, and we will also create boundary layer mesh that can be used to efficiently capture the near-wall fluid flow behavior.
