Simulation and Modeling of Using UDF in Moving Deforming Mesh DOF by ANSYS Fluent
In the previous workshops, all the motions were imposed or controlled ones, so the flow reacted upon the structured motion.This tutorial illustrates how to handle a case where the flow influences the motion of an element.To do so, it requires the use of a 6DOF (Degrees of Freedom) UDF (User Defined Function) that takes into account the forces & momentums acting on the solid in motion.This tutorial shows how to set up a case using this kind of model.
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.
- Reading and Checking the Mesh
- Specifying Solver and Analysis Type
- Specifying Dynamic Mesh Settings
- Run The Simulation
In this tutorial you have learned one more step in the process of setting up a moving deforming mesh, how to move an object according to fluid flow influence.
To run such an application, you need to use the 6DOF UDF.
- First write the appropriate UDF by defining the properties of the 6DOF and compile it.
- Next enable the Six DOF option in the Dynamic Mesh model and define the Gravitational Acceleration.
- Lastly define correctly which zones are actively involved in the evaluation of the forces and momentums.
