Setting Up Monitors

Create reports to monitor the displacement of the upper corners of the plate in the x-direction, the traction load, and the moment about the z-axis, during the co-simulation.

To monitor the displacements of the upper-left and upper-right corners of the plate, two point-probes must be created that follow the motion of the corners as the plate moves in the flow.
  1. In the Graphics window, click the Mesh Scene 1 tab.
  2. Right-click the Derived Parts node and select New > Probe > Point
  3. In the Create Point Probe dialog, set the properties as follows:
    Property Setting
    Input Parts Regions > plateFluid > Boundaries > Plate FSI
    X 0.0 m
    Y 0.04 m
    Z 0.1 m
    Display No Displayer
  4. Click Create then Close.
    A node, Point, is added beneath the Derived Parts node.
To create another point probe for the other corner:
  1. Copy the Derived Parts > Point node and paste it onto the Derived Parts node.
  2. Rename the Derived Parts > Point node to Upper +Y, and the Derived Parts > Point copy to Upper -Y.
  3. Edit the Upper -Y node and set Point to [0.0, -0.04, 0.1] m,m,m.
To make the points move with the plate when the morpher moves the mesh:
  1. Multi-select the Upper +Y and Upper -Y nodes and activate Follow Motion.
Having created point probes on the upper corners of the plate, you can now create reports that report the displacement of these corners:
  1. Right-click the Reports node and select New > User > Maximum.
  2. Rename the Reports > Maximum 1 node to X Displacement Upper +Y.
  3. Set the following properties:
    Property Setting
    Field Function Co-Simulations > Co-Simulation: Displacement > Laboratory > i
    Parts Derived Parts > Upper +Y
    Smooth Values Activated
  4. Create another Maximum report for the other corner.
  5. Rename the report that you just created, Reports > Maximum 1, to X Displacement Upper -Y.
  6. Set the following properties:
    Property Setting
    Field Function Co-Simulations > Co-Simulation: Displacement > Laboratory > i
    Parts Derived Parts > Upper -Y
    Smooth Values Activated
Use the displacement reports to create monitors and a plot:
  1. Multi-select the X Displacement Upper +Y and X Displacement Upper -Y reports.
  2. Right-click one of the reports and select Create Monitor and Plot from Report.
  3. In the Create Plot From Reports dialog, select Single Plot.


    The report monitors are displayed under the Monitors node, and the plot is shown under the Plots node.
  4. Rename the Plots > Reports Plot node to Displacement Plot.
Create two more reports to monitor the traction load and moment on the plate:
  1. Right-click the Reports node and select New > Flow/Energy > Force.
  2. Select the Reports > Force 1 node and set the following properties:
    Property Setting
    Direction [1.0, 0.0, 0.0] (default)
    Force Option Pressure + Shear (default)
    Parts Regions > plateFluid > Plate_FSI
  3. Right-click the Reports node and select New > Flow/Energy > Moment.
  4. Select the Reports > Moment 1 node and set the following properties:
    Property Setting
    Axis [0.0, 0.0, 1.0] (default)
    Force Option Pressure + Shear (default)
    Parts Regions > plateFluid > Plate_FSI
Create two separate plots for the force and moment reports:
  1. Multi-select the Force 1 and Moment 1 reports.
  2. Right-click and select Create Monitor and Plot from Reports.
  3. In the dialog that appears, select Multiple Plots (one per report).
Finally, verify the trigger for monitoring the data is set to time-step:
  1. Expand the Monitors node and multi-select the four report monitors.
  2. Make sure that Trigger is set to Time Step.
  3. Open all plots.
  4. Save the simulation.
