Edge Attributes: Global Pressure
Description
Assigns uniform global pressure to selected geometry edges using three orthogonal components and a coordinate system.
When the geometry is automeshed, plates created along the geometry edge will inherit the edge global pressure attribute (see Plate Attributes: Edge Global Pressure).
The magnitude of the resultant force is equal to pressure × edge length × membrane (or equivalent) thickness.
In geometric nonlinear analysis, the direction of the pressure does not change as the plate deflects and deforms.
Pressure attributes are load case dependent.

Global Pressure X / Y / Z
Three components of pressure.
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.
