Overset Meshing Technology for the A&D Industry

A common difficulty in simulating CFD problems with large relative motion between components is how to adequately handle the mesh deformation. These problems have largely been handled through complicated remeshing or mesh smoothing methods. Overset meshing provides an alternative approach to these problems. Additionally, overset meshing may be useful for certain geometries that may be better represented by separate component meshes or for design exploration studies involving repetitive reconfiguration of parts. In this webinar, we discuss the basics of overset meshing in Ansys Fluent and present best practices. We will also review recent validation studies and novel example cases for external aerodynamics, projectile motion, store separation and marine applications.
