Inlet

Use the Inlet feature to set the inlet condition to normal inflow velocity, pressure, or zero pressure.

E D G E O R P O I N T S E L E C T I O N

From the Selection list, choose the geometric entity (edges or points) to define the inlet. The default setting is to include all edges or points in the model.

P A I R S E L E C T I O N

If Inlet is selected from the Pairs menu, choose the pair to define. An identity pair has to be created first. Ctrl-click to deselect.

I N L E T S E T T I N G S

Select an Inlet condition—Normal inflow velocity, Pressure, or Zero pressure.

•If Normal inflow velocity is selected, enter a Normal inflow velocity U0 (SI unit: m/s). The default is 0.

•If Zero pressure is selected, this defines pf 0 on the edge/point.

•If Pressure is selected, enter a Pressure pf,0 (SI unit: Pa) to define pf pf,0 on the edge/point. The default is 0.

Outlet

The Outlet feature includes a set of boundary conditions describing fluid flow conditions at an outlet.

E D G E O R P O I N T S E L E C T I O N

From the Selection list, choose the geometric entity (edges or points) to define the outlet. The default setting is to include all edges or points in the model.

P A I R S E L E C T I O N

If Outlet is selected from the Pairs menu, choose the pair to define. An identity pair has to be created first. Ctrl-click to deselect.
