Set up a particle tracking simulation

1. Click Home tab→Loads and Conditions group→Simulation Object Type list →Particle Injection .

2. In the Region group, click Select Object and select the polygon free faces or mesh element free faces where the particles are injected.

3. (Optional) In the Parameters group, select Mass and Size Options check box to define mass and size of the injected particles and do the following steps:Specify the Mass and Diameter of the particles.From the Drag list, select either Spherical Correlation or Specify to define particle drag.If you selected Specify from the Drag list enter the value for Drag Coefficient.

4. Select an option from the Inflow Density list to specify how particle inflow density is calculated.Your selection determines the options available in the Particle Injection dialog box.

5. Click OK.

6. In the Simulation Navigator, right-click the solution node and choose Edit.The Solution dialog box opens.

7. In the Ambient Conditions node, in the Gravity group, enter the value for the gravity and specify the gravity vector.

8. In the 3D Flow node, in the Flow Surface Parameters group, from the Default Particle Impact Type list, specify whether the particles stick to the wall or rebound.

9. (Optional) In the Results Option node, in the Optional Output Format group, select additional output formats: Tecplot, CGNS, and ParaView.

10. For the steady state analysis, set the particle tracking simulation parameters following these steps:In the Simulation Navigator, right-click the solution node and choose Edit Solver Parameters.The Solver Parameters dialog box opens.In the 3D Flow Solver node, expand the Particle Tracking Controls group.In the Steady State Injection Duration box, enter the duration of the particle injection into the fluid domain.From the Steady State Simulation Time list, match the injection duration or specify an alternate total time for the particle tracking simulation.From the Steady State Output Option list, select how the particle time step is defined.Depending on the option you selected in previous step, do one of the following:In the Number of Outputs box, enter the value for the number of particle time steps.In the Output Interval box, enter the value for the duration of the particle time step.

11. Solve the model.

12. Display the particle density results.
