This workflow describes how to define all of the individual components required to create a
simulation with Lagrangian particle physics.
- Activate particle modeling in the fluid physics of
the simulation, and specify whether the particles have mass. For more information,
see Defining Lagrangian Particles in Fluid Physics.
- Define a steady-state step or a transient step, and specify the coupling schemes for particle
momentum and energy in the step. For steady-state simulations you can also define
the post-steady-state particle time to specify how long particles will be tracked
once the flow solution has converged. For more information, see Defining Particle Controls.
- Specify the locations where particles enter the fluid regions. For more information,
see Specifying Particle Injection Sources.
- Specify how the inlets and mass flow split outlets in
your model interact with the particles:
- Reflection boundaries are locations where particles reflect off the inlet or
outlet surface.
- Termination boundaries are locations where particles leave the fluid
regions.
- Mixed boundaries are locations where a portion of particles reflect or
terminate. The proportion of reflection and termination at mixed boundaries
depends on the deposition model you specify.
For more information, see Defining a Particle Boundary.
- After you complete the remaining modeling and
scenario tasks, you can request field and history output about the particles and the
boundaries. For more information, see Defining Output Requests.
When the simulation results are available, you can plot contours of the selected output to
review the particle and boundary behavior.
