After entering a name for the subdomain, or selecting the subdomain to edit, the subdomain details view will be displayed. This contains two tabs, Basic Settings and Sources, that are accessed by selecting the tabs located across the top. You should complete each tab in turn, proceeding from left to right.
Note: Fluid sources are on their own tab.
Basic Settings: Sets the location and the coordinate frame for the subdomain. For details, see Basic Settings Tab.
Sources: Defines volumetric source terms in the subdomain for single-phase simulations, or volumetric source terms that apply to all fluids in a multiphase simulation. For details, see Sources Tab.
Fluid Sources: Defines volumetric source terms that apply to individual fluid in a multiphase simulation.
