<Dynamic Surface Loads>

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 the Load Set directly in the entry box, GTS  automatically creates the relevant Load Set.
 

Type

Face Pressure

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

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

Object

Type

Select a method of 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 previously defined loads on the selected nodes

Delete

Delete previously defined loads on the selected nodes

Apply to Unassigned Objects Only

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

Direction and Function

Specify the time forcing function, loading direction and arrival time.
 

Normal

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

Ref.CSys.-Axis 1

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

Ref.CSys.-Axis 2

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

Ref.CSys.-Axis 3

Apply the surface 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 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.

<For Direction>

It offers two methods to define the load direction. Check on the first option to select a direction from the Datum or Geometric Shape. The second option is to define the direction vector directly.
 

Function Name

Select a time forcing function defined in "Time Forcing Functions."
Load Type

Type of the selected time history forcing function.
Arrival Time

"Delay" time for the time forcing function
Scale Factor

Scale factor for the time forcing function
