Setting Up Evaporation Rate Reports, Monitors, and Plots

Set up reports, monitors, and plots to monitor the film evaporation rate along the fluid film boundary.

To set up evaporation rate reports, monitors, and plots:

  1. Right-click the Reports node and select New > Metrics > Surface Average.
  2. Rename the newly created Surface Average 1 node to H2O Evaporation Rate.
  3. Set the Scalar Field Function to Film Evaporation Rate > Film Evaporation Rate of H2O.
  4. Click the ellipsis to the right of the Parts property.
  5. In the dialog that appears, expand the Regions > Fluid node and select Wetted Wall [In-place 1].


  6. Click OK.

The H2O Evaporation Rate - Properties window looks as follows:



Copy this report to create a second one for the ethylene glycol evaporation rate:

  1. Right-click Reports > H2O Evaporation Rate and select Copy.
  2. Right-click Reports and select Paste.
  3. Select the copy and rename it to C2H6O2 Evaporation Rate.
  4. Select Reports > C2H6O2 Evaporation Rate and, set the Scalar Field Function to Film Evaporation Rate > Film Evaporation Rate of C2H6O2.

Create a monitor and a plot for both reports.

  1. Select both the H2O Evaporation Rate and C2H6O2 Evaporation Rate nodes, right-click either and select Create Monitor and Plot from Report.


  2. Click Single Plot to display both evaporation rates on the same plot.

Set the monitors to update at each time step:

  1. Select both the Monitors > C2H6O2 Evaporation Rate Monitor and the H2O Evaporation Rate Monitor nodes, and set Trigger to Time Step.


Format the monitor plot appearance:

  1. Rename Plots > Reports Plot to Evaporation Rates.
  2. Right-click the Plots > Evaporation Rates node and select Open.
  3. Select Plots > Evaporation Rates > Axes > Bottom Axis > Title and set the Title to Time (s).
  4. Select Plots > Evaporation Rates > Axes > Left Axis > Title and set the Title to Surface Average of Film Evaporation Rate (kg/m^2-s).
