As
a SolidNetWork license customer, you can control how to load the HVAC and Electronics
Cooling add-in modules for Flow Simulation using two
methods.
The first method lets you specify the default
behavior for the add-ins when you load Flow Simulation. The option Automatically load Flow Simulation add-in modules if
available is in the tab.
Clear this option if
you do not have a need for the Flow Simulation add-ins. The HVAC and
Electronics Cooling add-in modules do not load when Flow Simulation is added in with
existing methods.
The second method lets you override default behavior and
include the HVAC and Electronics Cooling add-in modules when you load Flow Simulation.
Click the Down arrow 
on SOLIDWORKS Flow
Simulation (SOLIDWORKS® Add-ins
toolbar) or SOLIDWORKS Flow Simulation with one or both of the
add-modules to load.
Without these methods, the licenses for the add-in modules are consumed whether or not
you need them and may be denied to other users on your network.
