Rather than using the volumes and ranges listed in the columns of the Gas Cloud Analysis window, you may opt to set your own:
Click the Custom Gas Clouds tab and select the Add button to open the custom gas cloud panel
Choose the Variable for the custom gas cloud, this example will use Methane Volume Fraction, %LFL
Set the Condition for the range of the variable to calculate: Greater than, Less than and Between options are available. Enter the associated value and click the Add button to create a column which will display the volume of gas for the variable and range you select. This example will use Greater than "60%LFL"
You will be prompted if you want to update the data now, click yes to view the results.
Tutorial 3 - Figure 31 - Creation of Custom Gas Clouds in the Gas Cloud Analysis Window
This will add a new column in the Custom Gas Clouds Tab. The results for the volume of gas >60%LFL for the case simulated in Tutorial 2 is shown below. The above steps can be repeated for other variables and other ranges of values.
