Overset Mesh Can Simplify and Speed Simulations with Moving Parts - Application Brief
A common difficulty in simulating complex fluid flow problems is that some geometries can not be well-represented using a single, contiguous mesh. In many cases, different geometrical features are best represented by different mesh types. Preparing this mesh can be time consuming and complicated. Additionally, the large, poorly structured meshes that result can take excessive time to solve and can result in reduced accuracy.
