Convert Study Example (C#)

This example shows how to convert a static study to a linear dynamic harmonic 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. Open public_documents\samples\Simulation Examples\tutor1.sldprt.
//
// Postconditions:
// 1. Converts the Ready study to the LinDynHarmonic study.
// 2. Sets damping options for, meshes, and analyzes LinDynHarmonic.
// 3. Inspect the Simulation study tree.
//
// NOTE: Because the model is used elsewhere, do not save changes.
