Load: Pressure Load

Function

Apply pressure loads to the faces or edges of plate, plane stress, plane strain, axisymmetric or solid elements. Modify or delete previously entered loads.

Call

Model > Load > Pressure Load

<Pressure Load>

Load Set

Select a Load Set in which the specified load is included
Click to the right to prompt the Define Load Set dialog box to add, modify or delete Load Set. If the user types the name of Load Set directly in the entry box, GTS will automatically create the relevant Load Set.
 

Type

Face Pressure

Pressure loads will be applied on the faces of 2D or 3D elements.
Edge Pressure

Pressure loads will be applied on the edges of 2D or 3D elements.
 

Object

Type

Select a method for selecting a part where the loads will be assigned..
 

Surface

Select Surfaces on which the loads will be applied.

Element

Select 2D elements on which the loads will be applied.

Element-Face

Select 3D element faces on which the loads will be applied.
 

Mode

Add

Add new loads to the selected nodes

Replace

Replace the previously defined loads on selected nodes

Delete

Delete the previously defined loads on selected nodes

Apply to Unassigned Objects Only

When adding new loads, this option applies loads only to unassigned nodes.
 

Direction

Select the direction of the pressure loads to be applied.
 

Normal

Apply the pressure load in the normal direction of the selected object.

Ref.CSys.-Axis 1

Apply the pressure load in the first direction of the reference coordinate system.

Ref.CSys.-Axis 2

Apply the pressure load in the second direction of the reference coordinate system.

Ref.CSys.-Axis 3

Apply the pressure load in the second direction of the reference coordinate system.

Direction

Select the load direction from a Datum or a Geometric Shape.
 

<For Ref.CSys.-Axis 1, 2, or 3>

Ref. CSys

Select the coordinate system which becomes the reference for the load components. Click button to the right to prompt the Create/Modify Coordinate System dialog box to add, modify or delete the reference coordinate system.

<For Direction>

Two options are available for defining the force direction. Check on the first option to select a direction from Datum or Geometric Shape. The second option is to define the direction vector directly.
 

Projection

When the pressure loads are applied to plate or solid elements in the direction of the reference coordinate system, select whether or not to project the loads on a plane perpendicular to the loading direction.

Yes

Project the pressure loads
No

The pressure loads are applied along the entire face
Uniform

The pressure loads are uniformly distributed.
P or P1

Enter the pressure load value. If it is not uniform, the pressure load value is applied at the first node.
Base Function

If the pressure load is defined using a function, select the relevant function. Click button to prompt the Create/Modify Function dialog box.
P2~P4

When the pressure load varies linearly, enter the pressure load values at each element node.
