Vent BC is used specify where the air is vented out and resin will eventually emerge out when the mold is filled (or earlier in the case of race tracking). Often, pressure is set to 0 at the vent.

Variable

Default Value

Valid Range

Data Type

Significance

PortLocation

(0, 0, 0)

Valid (x, y, z)

Constant

This is needed only if gravity is turned on.

Pressure

None

+ve value

Constant or function of time

Pressure is specified in Pa. You should specify at least Pressure or SuctionRate. If you specify both, then Pressure will be given priority.

SuctionRate

None

+ve value

Constant or function of time

SuctionRate is specified in m3/s. You should specify at least Pressure or SuctionRate. If you specify both, then Pressure is given priority.

Temperature

None

T > 273

Constant or function of time

This needs to be specified only if the Heat Transfer is on. If you specify Temperature, you should not specify heat flux and the vice versa.

HeatFlux

0

+ve, 0, or -ve value

Constant or function of time

This needs to be specified only if the Heat Transfer is on. If you specify Temperature, you should not specify heat flux and the vice versa.

 

Syntax


VentBC bc_name {

PortLocation = X Y Z

( Pressure | SuctionRate ) = value

[ ( Temperature | HeatFlux ) = value ]

}

 

Example


VentBC vent1 { PortLocation = 0.5 0.5 10.0

         Pressure = 0.0

         HeatFlux = 0.0 }
