The procedure for setting up the GT-Power coupling in
FLUENT is presented below.
Read in the mesh file and define the models, materials, and boundary zone types (but
not the actual boundary conditions), noting the requirements and restrictions listed in Section
Specify the location of the GT-Power data and have
FLUENT use them to generate user-defined functions for the relevant boundary conditions (using the
1D Simulation Library panel, shown in Figure
Figure 7.29.1: The
1D Simulation Library Panel
GTpower in the
1D Library drop-down list.
Specify the name of the GT-Power input file in the
1D Input File Name field.
When you click
Start, GT-Power will start up and
FLUENT user-defined functions for each boundary in the input file will be generated.
Set boundary conditions for all zones. For flow boundaries for which you are using GT-Power data, select the appropriate UDFs as the conditions.
Note that you must select the same UDF for all conditions at a particular boundary zone (as shown, for example, in Figure
7.29.2); this UDF contains all of the conditions at that boundary.

If you plan to continue the simulation at a later time, starting from the final data file of the current simulation, specify how often you want to have the case and data files saved automatically.
To use a GT-Power restart file to restart a
FLUENT calculation, you must edit the GT-Power input data file. See the GT-Power User's Guide for instructions.
Continue the problem setup and calculate a solution in the usual manner.
