Reviewing the Simulation Summary


The full scenario matrix generated from the information entered in the leak frequencies and wind conditions tab is shown on the Simulation Summary tab.


The total number of scenarios is listed on the upper-right corner of the window - 120 cases for this tutorial. We will return to this table after the simulations have completed to add a consequence value based on the flammable mass of the resulting gas cloud for each case, alternatively you may manually enter a consequence value using the Property editor at the bottom of the window.


Note: frequency and consequence information may be added before or after simulations have complete.

Clicking the top of the Frequency column will sort the cases by their associated frequencies. It can be decided if the likelihood of a case is too low to include it in the analysis. Desired cases can be added by selecting a group of simulations using the Shift key and clicking the Add to Project button.


If HVAC or Fans have been defined in the project (via the Add Items Tab) a dropdown menu will appear on the right side of the Simulation Summary tab to allow for HVAC to be selected and added to the simulations. If no HVAC has been defined this option will not appear.


For this tutorial, all defined cases will be added to the project, proceed by performing the following:

  1. On the right side of the window, set the Type to Dispersion

  2. Ensure the Run Now checkbox is unchecked and click Add to Project at the bottom right of the Risk Manager Window.

  3. The ground level may need to be defined at this point. If prompted, click OK and set the ground height at 0m, to match the ground CAD item defined earlier and press Confirm

  4. Click Yes in the window that appears to add 12 ventilation and 120 dispersion cases to the project.


132 cases will now be listed in the Project Items Tab. Save your project before continuing to define a risk data set and monitor region.
