  - DEM Particle Settling
    This tutorial simulates a three-dimensional solid flow through a model blast furnace to predict the formation of the deadman region at the base of the furnace.
    - Importing the Surface Mesh and Naming the Simulation
      Start a new simulation and import blastFurnaceSurfaceMesh.dbs.
    - Generating the Volume Mesh
      Use the surface remesher and polyhedral volume mesher to create a mesh with a base size of 0.01 m, as the fluid solution is not of particular importance for this tutorial.
    - Selecting Physics Models
      Physics models are required to define the behavior of the multiphase continua.
    - Defining Lagrangian Phases
      A Lagrangian phase is used to define the solid particles in the simulation. The phase requires specific physics models and properties to characterize its behavior. In this case, the solid particles are glass beads, with the material properties defined manually.
    - Defining the DEM Particle Interaction
      The DEM particle interaction is used to define how the particles behave when they collide with one another and wall regions. The procedure to define the ORE to ORE interaction has been provided in detail, with a table summarizing the steps for ORE to wall interaction.
    - Setting Reference Values
      The reference values must be defined to make sure that the acceleration due to gravity acts in the expected direction.
    - Setting the Boundary Conditions
      By default, the conditions for boundaries representing the furnace are all set to no-slip walls. You now change the pIn boundary to Outlet with default Split Ratio of 1 to allow filling of the geometry with particles for the first 11.5 seconds of the simulation.
    - Creating an Injector
      Particles are injected into the fluid region from the top of the blast furnace. The particles, 0.01 m in diameter, are injected at a mass flow rate of 18.33 kg/s with a velocity of 0.01 m/s in the negative Y-direction.
    - Setting the Solver Parameters and Stopping Criteria
      As the simulation is transient, the solver time-step and actual run time must be set. In this case, the time-step is 0.01 seconds, with a physical time of 11.5 seconds for the first stage of the simulation. Also as no fluid flow effect is taken into account, freeze the coupled implicit solver.
    - Setting Up a Visualization Scene
      A scalar scene is created to provide a visual representation of the glass beads within the fluid system.
    - Running the Simulation
      The simulation is now ready to be run.
    - Visualizing Results
      When the solver is complete, the Scalar Scene 1 in the Graphics window appears.
    - Stage Two of the Simulation
      Having filled the furnace with beads in stage 1, it is now necessary to allow a period for the beads to settle before opening the outlets and allowing the beads to escape.
    - Stage Three of the Simulation
      For this final stage of the simulation, open the outlets (one on each side) to allow the particles to discharge. Also, the inlet to allow new particles to enter the furnace to supplement the exiting ones already in the furnace.
    - Comparing the Results
      In this section, compare the height and shape of the deadman region with the experimental image of Zhou et al. To show the deadman region more clearly, you create the user-defined field function, oldParticles, which displays the particles with residence times of less than 36.5 s all in the same color.

Use the following steps:

Navigate to the Regions > Region > Boundaries node.

Edit blastFurnaceSurfaceMesh.pIn and set the following properties:


Node	Property	Setting
blastFurnaceSurfaceMesh.pIn	Type	Outlet
