Assign the pressure

Ver: 0
 

DESCRIPTION

For an incompressible fluid, imposing a normal surface force on any part of the boundary implicitly defines a reference pressure. If, however, a normal surface force has not been imposed anywhere along the boundary, one must specify the pressure at one point in the domain.

The user selects a spatial position and a value of the pressure. The pressure is imposed at the closest node to the given selected position.

  OPTIONS

i
 Pressure condition for velocity field  i
Selecting this option allows the user to choose the point where the pressure is imposed. The default vaue is (0,0,(0))
