Apply Table-driven Load to Multiple Beams Example (C#)

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 file to open 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.
