Load: Prescribed Displacement

Function

Enter prescribed (forced) nodal displacements, or modify or delete previously entered prescribed (forced) displacements.

Call

Model > Load > Prescribed Displacement

<Prescribed Displacement>

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.
 

Object

Type

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

Curve

Select Curves on which the loads will be applied.

Surface

Select Surfaces on which the loads will be applied.

Node

Select the nodes directly.

Free Face Node

Select the nodes of free face of the selected element. All nodes within the defined angle (Feature Angle) from a seed node will be assigned. 

Free Face Node

It becomes active when the Free Face Node selection method is designated.
 

Seed Node

Select a Seed Node which becomes the reference for determining the free face.
Feature Angle

When the free face selection is expanded from the Seed Node, it only selects element nodes within the specified Feature Angle.
 

Click to select the free face nodes, and they will appear on the screen.
 

Mode

Add

Add new loads to selected nodes

Replace

Replace previously defined loads on selected nodes

Delete

Delete previously defined loads on selected nodes

Apply to Unassigned Objects Only

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

 

Ref. CSys

Select the coordinate system which becomes the reference of 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.
 

Base Function

If the prescribed displacement is applied using a function, select the relevant function. Click button to prompt the Create/Modify Function dialog box.
 

T1

Enter the first direction component (X or R) of the prescribed displacement in the reference coordinate system

T2

Enter the second direction component (Y or q) of the prescribed displacement in the reference coordinate system.

T3

Enter the third direction component (Z) of the prescribed displacement in the reference coordinate system.

R1

Enter the prescribed rotation component about the first axis (X or R) in the reference coordinate system.

R2

Enter the prescribed rotation component about the second axis (Y or q) in the reference coordinate system.

R3

Enter the prescribed rotation component about the third axis (Z) in the reference coordinate system.
