Apply Table-driven Load to Multiple Beams Example (VB.NET)

This example shows how to apply a table-driven elliptical load to multiple beams on a part.

'-------------------------------------------------------------
' Preconditions:
' 1. Add the SOLIDWORKS Simulation as an add-in (in SOLIDWORKS, click 
'    Tools > Add-ins > SOLIDWORKS Simulation > OK).

' 2. Add the SOLIDWORKS Simulation primary interop assembly as a reference
'    (in the IDE, click Project > Add Reference > .NET > 
'    SolidWorks.Interop.cosworks > OK).

' 3. Open the Immediate window.
' 4. Ensure that the specified part exists.
'
' Postconditions:
' 1. Applies a table-driven elliptical load to the part
'    and prints its type and other force-related values
'    in the Immediate window.
' 2. To verify, examine the External Loads folder
'    in Study 3 in the Simulation tree.
' 3. Examine the Immediate window.
'
NOTE: Because this part document is used elsewhere,
' do not save any changes when closing it.
