1.3 Limitations

Although the UDF capability in ANSYS FLUENT can address a wide range of applications, it is not possible to address every application using UDFs. Not all solution variables or ANSYS FLUENT models can be accessed by UDFs. If you are unsure whether a particular problem can be handled using a UDF, contact your technical support engineer for assistance.

Note that you may need to update your UDF when using a new version of ANSYS FLUENT.
