|| This completes the problem specification.

Click on the '''Solve''' button in the toolbar area.
|-
|| Point to '''Messages''' at the bottom
|| Once the calculations are complete, we can see an error message at the bottom.

It says, '''Error in ‘Flash’: The current calculation mode requires an Energy Stream to be connected to the Unit Operation.'''

This error message means we must connect an energy stream to the '''Gas-Liquid Separator'''.
|-
|| '''Flash (Gas-Liquid Separator) '''property editor window >> Point to '''Energy Stream'''

'''Click >> Create and Connect'''
|| This can be done in two ways.

We can drag an '''Energy Stream''' from the '''Stream''' section of the '''Object Palette''' and drop it near the '''Gas-Liquid Separator'''.
Alternatively, we can also click on the yellow icon next to the drop-down against '''Energy Stream'''.

It will automatically '''Create and Connect''' an '''Energy Stream''' to the '''Gas-Liquid Separator'''.

Let us do that.
