The following procedure provides an overview of the steps required for setting up and solving an MPM case. Only the steps that are pertinent to MPM are shown here. For information about inputs related to other models that you want to use in conjunction with the MPM, see the appropriate sections for those models in the Ansys Fluent User's Guide.
Select the Solution workspace in the Fluent Launcher.
Click Mesh (under Getting Started With...) to select a 3D mesh file and click .
Scale the mesh, if necessary.
For most cases except for cemented particles simulations, select the Transient solver from the Time list in the General task page.
Define the boundary conditions and physical properties for fluid flow as usual.
(optional) Initialize the flow variables and run the flow simulation until the flow converges.
This step could be performed to improve solution stability. Using a converged flow solution as a starting point for an MPM simulation can be particularly helpful in situations where there is a strong influence of macroscopic particles on the fluid flow.
Use the Macroscopic Particle Model dialog box to specify the parameters for the MPM simulation.
Initialize either the MPM as described in the sections that follow or the flow field in the usual way.
Run the MPM simulation.
Save the case and data files, if desired.
Review the simulation results by generating plots or alphanumeric reports using the Ansys Fluent postprocessing facilities.
