Simulation of Use of Events in the Dynamic Mesh Module

Simulation of Use of Events in the Dynamic Mesh Module by ANSYS Fluent

Introduction

This tutorial illustrates the integration of additional functions through the use of Events, which are available with the Dynamic mesh module.The events not only allow to adjust more realistically the motion of parts (or sub-parts) in regard to the whole system, but they can also help on the meshing and/or solver aspect, and so on.
In addition to this, you will also go through the use of the In-Cylinder built in function.
And finally you will combine the 3 mesh method (smoothing, layering, remeshing) on a 3D example.
This tutorial is written with the assumption that you are familiar with the ANSYS Fluent tree and menu structure. Some steps in the setup and solution procedure will not be shown explicitly.

  • Preparation
  • Combine Mesh Method and In-Cylinder Function
  • Events: Insert/Remove Boundary Layer
  • Events: Insert/Remove Interior Layer and Executing a Command
  • Changing the Time Step

Summary

In this tutorial you have gone through the whole process to set the (MDM) moving deforming mesh model.

  • You have learned how to use the all the three different methods together.
  • You have integrated the In-Cylinder option, in which you can check how the elements have influence, especially the crank radius and connecting rod.
  • You also could experiment with the speed.
  • In order to better prepare the motion of the parts of the application, you learned how to use the events to set up and control mesh motions correctly.
