Ansys Fluent Dynamic Mesh Modeling

Course Overview

This course teaches how to run simulations using the dynamic mesh model and overset meshes in Ansys Fluent. The dynamic mesh model can be used to model flows where the shape of the domain is changing with time due to motion on the domain boundaries.  Combined with the six degrees of freedom (6 DOF) solver, dynamic mesh allows the trajectory of a moving object to be determined by the aero or hydrodynamic forces from the surrounding flow field.  Overset meshing allows complex geometrical problems to be decomposed into a system of geometrically simpler overlapping meshes. Overset and dynamic meshing can be applied to a wide variety of applications, from automotive and aerospace to chemical and environment industries. Throughout this course, you will learn all aspects of the model, starting with the different motions, the mesh mechanism, the use of subroutines, and the workflow to set up cases easily and quickly.
