3.2 Loading the Population Balance Module

The population balance module is loaded into ANSYS FLUENT through the text user interface (TUI). The module can only be loaded when a valid ANSYS FLUENT case file has been set or read. The text command to load the module is

define $\rightarrow$ models $\rightarrow$ addon-module.

A list of ANSYS FLUENT addon modules is displayed:

FLUENT Addon Modules:
	0. none
	1. MHD Model
	2. Fiber Model
	3. Fuel Cell and Electrolysis Model
	4. SOFC Model with Unresolved Electrolyte
	5. Population Balance Model
Enter Module Number: [0] 5

Select the Population Balance Model by entering the module number 5. During the loading process a scheme library containing the graphical and text user interface, and a UDF library containing a set of user defined functions are loaded into ANSYS FLUENT. A message Addon Module: popbal...loaded! is displayed at the end of the loading process.

The population balance module setup is saved with the ANSYS FLUENT case file. The module is loaded automatically when the case file is subsequently read into ANSYS FLUENT. Note that in the saved case file, the population balance module is saved with the absolute path. Therefore, if the locations of the population balance module installation or the saved case file are changed, ANSYS FLUENT will not be able to load the module when the case file is subsequently read.
