Dynamic Mesh Concepts in ANSYS Fluent

Introduction to Dynamic Mesh Concepts

This video aims to talk about Dynamic Mesh Concepts. This lesson will give you a general introduction to the dynamic mesh and an overview of available sections of dynamic mesh settings in ANSYS Fluent.

This product is the first chapter of the Dynamic Mesh Training Course.

We introduce the working environment of the dynamic mesh model in three different sections. This introduction will be detailed and comprehensive, So you will not have any questions after reading it.

In the first section, we will introduce you to Mesh Update Methods. When the computational zone or its boundaries are moved or deformed, how are the meshing of the model and its cells updated?

There are three mesh update methods available:

• Smoothing (spring/Laplace/boundary layer, diffusion, linearly elastic solid)
• Layering
• Remeshing (local cell, local face, face region, 2.5D)

In the second section, we will introduce you to the Options part of the dynamic mesh model. Here, we can use unique dynamic mesh models according to the modeling of our case study.

These Options include:

• In-Cylinder
• Six DOF
• Implicit Update
• Contact Detection

In the third section, we will introduce you to Dynamic Mesh Zone. Here, we determine the movement or deformation of the dynamic zones. In the settings of this section, we specify how the boundaries move or how the zones deform.

The types of dynamic behaviors available to apply to boundaries and regions are:

• Stationary
• Rigid Body
• Deforming
• User-Defined
• Coupling System
