Brick Attributes: Face Global Pressure
Description
Assigns uniform global pressure to selected faces of brick elements using three orthogonal components and a coordinate system.
In geometric nonlinear analysis, the direction of the pressure does not change as the brick deflects and deforms.
Pressure attributes are load case dependent.

Global Pressure X / Y / Z
Three components of pressure .
Projected
If set, the pressure acts on a projected area.
If not set, the pressure acts over the entire brick face surface area.
Two projection methods are available:
-
Components
Each pressure component in the global Cartesian coordinate system acts independently. Each component is applied over the projection of the brick face onto a plane normal to the pressure direction.
-
Resultant
The pressure acts over the projection of the brick face onto a plane normal to the direction specified by the vector composed of the three component values.
In geometric nonlinear analysis, the total load generated for projected pressure can change depending on the deflection and deformation of the brick, although the direction remains constant.
Coordinate System
The coordinate system (UCS) in which the pressure components are defined.
The UCS is used only to define the global Cartesian components of the force. Subsequent changes to the UCS do not affect the direction or magnitude of the force.
