Add Component Contacts Example (C#)

This example shows how to add component contacts 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 material library exists.
// 4. Ensure that the specified model document exists.
// 5. Open the Immediate window.
//
// Postconditions:
//  1. Opens the model.
//  2. Creates Frequency 1 study.
//  3. Uses a soft spring to stabilize the model.
//  4. Adds Component Contact-1 and Component Contact-2 to the
//     Component Contacts folder in the Simulation study tree.
//  5. Prints the component contacts' properties to the Immediate window.
//  6. Applies ductile iron to the model.
//  7. Meshes the model.
//  8. Analyzes Frequency 1.
//  9. Prints the resonant frequencies of each mode to the Immediate window.
// 10. Inspect the Immediate window, the Simulation study tree, and the
//     graphics area.
//
// NOTE: Because the model is used elsewhere, do not save changes.
