Visualizing the DEM Particles in Motion

You create a visualization scene that displays the DEM particles colored with their velocity magnitude together with the velocity magnitude of air on a cross-section of the cylindrical reactor. To be able to create an animation of the fluidized bed, you set up a solution history file. Both the visualization scene and the solution history file have been created on the starting file for your convenienvce, but you are required to complete the setup.

To visualize the DEM particles:
  1. Create the parcel and particle count reports:
    1. Right-click the Reports node and select New > User > Element Count and rename the new report to Element Count Parcels.
    2. Select the Element Count Parcels node and set Parts to Lagrangian Phases > Particle.
    3. Right-click the Reports node and select New > User > Sum and rename the new report to Sum Particle Count.
    4. Select the Sum Particle Count node and set the following properties:
      PropertySetting
      Field FunctionParticle > Particle Count
      PartsLagrangian Phases > Particle
  2. Set up the DEM scene:
    1. Open the Scenes > DEM Scene and select the Scene/Plot tab.
    2. In the toolbar, click Save-Restore-Select Views () and select Standard Views > (-Y) left.
    3. In the toolbar, click Reset View () to adjust the positioning of the reactor so that it fits fully within the scene.
    4. Expand the Scalar Fluid node and set the following properties:
      NodePropertySetting
      PartsPartsDerived Parts > Plane Section
      Scalar FieldFunctionVelocity > Lab Reference Frame > Magnitude
      Auto RangeOff
    5. Expand Scalar Particles node and set the following properties:
      NodePropertySetting
      PartsPartsLagrangian Phases > Particle
      Scalar FieldFunctionParticle > Particle Velocity > Magnitude
      Auto RangeOff
  3. Create annotations for the scene using the reports:
    1. In the Simulation tab, right-click the Tools > Annotations node and select New > Simple Text.
    2. Rename the User node to Particle Data.
    3. Select the Particle Data node and set the following properties:
      PropertyValue
      Text
      Particles: $SumParticleCountReport
Parcels: $ElementCountParcelsReport
      Default Height0.1
    4. Drag the Particle Data node to the top-left corner of the DEM scene.
    5. Drag the Solution Time node into the bottom-left corner of the scene.
      The final scene should look like this:

  4. Set up the solution history file so that after the simulation has run, you can animate the results:
    1. Select the Solution Histories > fluidizedBed_start node and set the following properties:
      PropertyValue
      FunctionsParcel > Parcel Index
      Particle > Particle Velocity > Magnitude
      Velocity > Lab Reference Frame > Magnitude
      InputsDerived Parts > Plane Section
      Lagrangian Phases > Particle
  5. Save the simulation.
