Parts-Based Meshing External Aerodynamics
This tutorial demonstrates how to set up a simulation using the parts-based meshing approach.
Parts-based meshing is a method for generating surface and volume meshes on geometry parts. It is different to region-based meshing in that it uses a series of mesh operations to define the process from the initial geometry to the final volume mesh. Having a series of operations allows you to modify the initial geometry and repeat the entire process with no additional inputs. This makes parts-based meshing particularly suitable for parametric design studies.
In this tutorial, you generate a volume mesh that is suitable for an external aerodynamics analysis of a car using the parts-based approach. Each step in the tutorial highlights some of the differences between parts-based meshing and region-based meshing. As part of the tutorial, you replace the rear wing on the prototype class racing car. Local surface remeshing only remeshes surfaces in the predefined area of the fluid domain, reducing the total amount of time needed to remesh the geometry.
