You can use a stand-alone Fluent session to define a reduced order model (ROM) for production in the Ansys Workbench environment (through Ansys DesignXplorer).
You can create a ROM from a series of 2D or 3D simulations. The ROM is a mathematical approximation of your full model, where you can change some inputs and get the solution immediately. These inputs are defined as input parameters in Ansys Fluent and can be material properties, inlet velocities, pressures and so on.
The process of creating and analyzing ROMs can be broken into two parts:
ROM Production—You can setup a ROM case in stand alone Fluent and read this case into Fluent in Workbench, as described in Defining a ROM and ROM Production in the DesignXplorer User's Guide.
ROM Consumption—The produced ROM can be consumed by exporting the ROM as either an FMU 2.0 file or a ROMZ filein, see ROM Consumption in the DesignXplorer User's Guide for more detials.
To learn more about ROMs, refer to Using ROMs in the DesignXplorer User's Guide.
