32.3.34 Define/User-Defined/Function Hooks...

The Define/User-Defined/Function Hooks... menu item opens the User-Defined Function Hooks panel.



User-Defined Function Hooks Panel


The User-Defined Function Hooks panel allows you to specify user-defined functions (UDFs) connected to a number of models and procedures in FLUENT. See the separate UDF Manual for details.

You can hook multiple UDFs to the following functions:

Controls

Initialization   

Adjust   

Execute At End   

Read Case   

Write Case   

Read Data   

Write Data   

Execute at Exit

Controls

Initialization   selects a UDF that is called immediately after you initialize your flow field.

Adjust   selects a UDF that is called at the beginning of an iteration before solution of velocities, pressure, and other quantities begins.

Execute At End   selects a UDF that is called at the end of an iteration or time step.

Read Case   selects a UDF that defines a customized section that is to be read from the case file.

Write Case   selects a UDF that defines a customized section that is to be written to the case file.

Read Data   selects a UDF that defines a customized section that is to be read from the data file.

Write Data   selects a UDF that defines a customized section that is to be written to the data file.

Execute at Exit   selects a UDF that is called when exiting a FLUENT session.

Wall Heat Flux   selects a UDF that modifies the way that the solver computes the heat flux between a wall and the neighboring fluid cells.

Net Reaction Rate   selects a UDF that defines the net reaction rate.

Volume Reaction Rate   selects a UDF that defines a volumetric reaction rate.

Surface Reaction Rate   selects a UDF that defines a surface reaction rate.

Particle Reaction Rate   selects a UDF that defines a particle reaction rate.

Turbulent Premixed Source   selects a UDF that defines the turbulent flame speed and source term for the premixed or partially premixed combustion model.

Chemistry Step   selects a UDF that defines the chemistry step function.

Spray Collide   selects a UDF that defines the spray collide function.

Cavitation Mass Rate   selects a UDF that defines the cavitation rate.

DO Source   selects a UDF that defines the discrete ordinate source function.

DO Diffuse Reflectivity   selects a UDF that defines the diffuse reflectivity function for the DO radiation model.

DO Specular Reflectivity   selects a UDF that defines the specular reflectivity function for the DO radiation model.
