Add Elastic Support Fixture Example (C#)

This example shows how to add an elastic support fixture to a frequency study.

//----------------------------------------------------------------------------
// 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. Ensure that the specified model document exists.
// 4. Open an Immediate window.
//
// Postconditions:
// 1. Opens the model.
// 2. Gets the Ready frequency study.
// 3. Deletes Fixture-1 from Ready.
// 4. Adds an Elastic Support-1 fixture to Ready.
// 5. Prints the properties of Elastic Support-1 to the Immediate window.
// 6. Meshes the model.
// 7. Analyzes Ready.
// 8. Prints the resonant frequency of each mode to the Immediate window.
// 9. Inspect the Immediate window, the Simulation Study tree, and the
//    graphics area.
//
// NOTE: Because the model is used elsewhere, do not save changes.
