25.2. Loading the MPM add-on Module

The MPM add-on module is installed with the standard installation of Ansys Fluent in a directory called addons/mpm. The module can be loaded only when a valid Ansys Fluent case file has been set or read.

Note:  The MPM is only available in 3D.

There are two different ways in which you can load the MPM module into Ansys Fluent:

  • Through the ribbon

    In the Physics ribbon tab, click More (Models group), and select Macroscopic Particle Model....

     Physics → Models → More → Macroscopic Particle Model...

    Once the MPM module is loaded into Ansys Fluent, the Macroscopic Particle Model dialog box opens where you can enable and set the MPM model as described in Modeling Macroscopic Particles.

  • Through the text user interface (TUI)

    Issue the following TUI command in the Fluent console:

    define → models → addon-module

    A list of Ansys Fluent add-on modules is displayed in the console:

    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
 6. Adjoint Solver
 7. Single-Potential Battery Model
 8. Dual-Potential MSMD Battery Model
 9. PEM Fuel Cell Model
 10.Macroscopic Particle Model
Enter Module Number: [0] 10 

    Select the Macroscopic Particle Model by entering the module number 10.

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 (UDFs) for the MPM add-on module are automatically loaded into Ansys Fluent. This process is reported in the Fluent console. Once the MPM module is loaded into Ansys Fluent, the Macroscopic Particles model appears under the Models tree branch, and the UDF library also becomes visible as a new entry in the UDF Library Manager dialog box. By default, the Macroscopic Particles model is enabled.
