9. Click Apply if the Auto Update checkbox is not selected, else the changes will be applied automatically.

You can modify the display of the particles in a similar way as that of the Geometry. In addition, the particles can be represented using a number of different forms, such as cones, streams, and vector that traces the direction in which the particles move.

1. Select the Particles subsection in the Analyst Tree.
2. Select Vector from the Representation type dropdown list.
3. Click Apply All.
4. Change the Time Steps to review the flow of the material.
5. Select Stream from the Representation type dropdown list.
6. Click Options.
7. In the Streams section, towards the bottom, select the Stream All Steps and Stream Fade checkboxes.

   
   
   

8. Click the icon to rewind the simulation.
9. Click the icon to view how the direction of movement of the particle changes over time.
10. Click the icon at any point and set the Representation type back to Default.

1. Select the Feed_Conveyor Geometry element in the Analyst Tree.
2. In the Coloring section of the Detailed View, select Velocity from the Color by dropdown list.
3. Set the Min, Mid, and Max colors to the Blue, Green, and Red respectively.
4. For Min Value and Max Value, select the Auto Update checkboxes.
5. Repeat the same steps for Receiving_Conveyor and Head_Pulley Geometry elements.
6. Click the icon to rewind the simulation, if required.
7. Click the icon to view the velocity of moving parts of the Geometry.
8. Before continuing, select the Geometries in the Analyst Tree.
9. In the Coloring section, select Uniform from the Color bydropdown list.
10. Select Color to Default from the Color dropdown list and then click Apply All.

1. Select Particles in the Particles subsection of the Analyst Tree.
2. In the Coloring section of the Detailed View, select Velocity in the Color by dropdown list.
3. Click next to the Min Value and Max Value fields to read the current values from the point in the simulation displayed in the Viewer.
4. Select the Auto Update checkbox so that the values continue to update while the simulation is being played.
5. Click Apply All to color the particles.
6. Select the rock particle in the Analyst Tree.
7. Select the Show Legend checkbox.
8. Click Apply.
9. Rewind the simulation back to the start and click the icon to view how the colors are updated as the simulation progresses.

You can examine the mass flow over time in the bottom conveyor by including a mass flow sensor.

1. Right-click Setup Selections in the Analyst Tree.
2. Select Add Sensor Selection > Mass Flow Sensor.
3. In the Representation section, set the Display Mode to Always.
4. Set the properties of the bin group as follows:

   
   
   

   
   
   

5. Click Apply.

You can also examine the increase of mass over time on the rock box. To do so, you will need to create a bin group over it.

1. Right-click Setup Selections in the Analyst Tree.
2. Navigate to Add Selection > Grid Bin Group and name it RockBox_group.
3. Select the newly created grid bin group and in the Detailed View, set its properties as follows:

   
   
   

4. Click Apply

A query is used to define a single element attribute, for example particle velocity, total force on a Geometry section, or number of collisions.

1. To determine the total mass of particles accumulating in the rock box, use the controls at the lower section of the Viewer window or type the current time to 0s (the beginning of the simulation, when no particles are present in the rock box).
2. Select Rock_Box_group in the Setup Selections section of the Analyst Tree.
3. In the Options section of the Detailed View, click Edit….

   The Selection Query Editor is displayed.

4. Expand Particle and then select Mass.
5. Select All from the Type dropdown list.

   You can also select one of the particles from the Type dropdown list to monitor only that particle type.

6. Set the Query Type to Total.
7. Select the Total Over Time checkbox and click the icon.
8. Click OK.
   The query is displayed in the dialog box.

   
   
   

1. In the Setup Selections section of the Analyst Tree, select Rock_Box_group.
2. In the Representation section of the Detailed View, click Edit... to edit the display options.

   The Display Options dialog box is displayed.

3. Select the On-Screen Query checkbox to display the mass in the Viewer:

   
   
   

4. Click the icon to view the results in real time.

   As the playback continues through the Time Steps, bin group data is collected and displayed.

1. Click the icon on the toolbar.
   Note: If you cannot see this icon on your toolbar, expand the Standard toolbar.
2. Select the Line tab and set the parameters as follows:

   
   
   

   1. In the X-axis tab, ensure that the Time Range covers the whole simulation time.
   2. In the Y-axis tab, set the Primary Attribute to Mass Flow Rate.
3. Click Create Graph to plot the graph.

   
   
   

The bin group over the rock box registers the change of total mass of the particles there.

1. In the Line tab, set the parameters as follows:

   
   
   

   1. In the X-axis tab, ensure that the Time Range covers the whole simulation time.
   2. In the Y-axis tab, set the Primary Attribute to Mass and the Component to Total.
2. Click Create Graph to plot the graph.

   
   
   

   Note: From the graph, you can conclude that a steady state has not yet been reached.
