Pressure Load

 

 

Define the (in-plane) Pressure Load in an Analysis model.

The Pressure Load may be a uniformly distributed Pressure Load or a linearly varying Pressure Load from the start to the end. Pressure loads are internally converted into equivalent Nodal Loads.

From the Main Menu, select Loads | Boundaries > Loads > Pressure Load pl_icon.gif

From the Command Line, type 'PressureLoad' or 'PL'

 

 

 

pl.gifLoad Set

Select the Load Set under which the Pressure Load has to be assigned . Click load_set.gif to invoke the Define Load Set dialog to Add, Modify or Delete Load Set(s).

 

Select Object

Select the objects to which Pressure Load will be assigned.

Element Boundary Curve

Select element edges to apply a Pressure Load along the edges.  

Curve

Select curves to apply Pressure Load which will be converted to Nodal Loads on the nodes associated with the selected curves.

 

Direction

Select the direction of the Pressure Load- Normal Direction, Global X or Global Z.

Load

Specify the type of Pressure Load.

Uniform

Linear

P1, P2

Pressure load magnitude (P2 becomes activated if Linear type of Load Value is selected.)

 

Function

Click fx.gif to define a function to specify a varying Pressure  Load.

Note: When Normal direction is selected, the + direction represents the direction from the outside of the element toward the inside of the element. In case of Global X or Global Z, the sign convention corresponds to the reference axes, +(→,↑) and - (←,↓).
