User Defined Functions (UDF) - Part 1 - An introduction to using UDF in ANSYS Fluent

User defined functions (UDF) allow you to modify the behavior of ANSYS Fluent to satisfy your particular modeling needs. For example, these modifications may be used to impose desired initial and boundary, material models as well as various physical and chemical transformations such as heat transfer, chemical reactions or phase change. UDFs are flexible and powerful, and allow you to use ANSYS Fluent as a framework to implement new models.

In this five part webinar series our aim is to present the fundamentals of developing UDFs. After a first webinar on the basic aspects of UDFs, we will deal with advanced topics such as UDFs for multiphase flow, Lagrangian Particle Tracking, reacting flow models and other advanced topics such as making your UDF's work in parallel.

The first part of this series is an introduction and review of UDFs. We will discuss the fundamental building blocks of a UDF with several examples. We shall also describe best practices for writing UDFs that are easy to maintain and allow them to work across various platforms.
