Create Trend Tracker Example (C#)

This example shows how to create a Trend Tracker for a static 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. Copy public_documents\tutorial\api\tjoint.sldprt to another name and replace
//    file_name in the code with the new name.
// Postconditions:
//  1. Opens the model document.
//  2. Gets the static study.
//  3. Meshes the model.
//  4. Sets the solver type.
//  5. Analyzes the study.
//  6. Click Yes if asked to save the model.
//  7. Adds Trend Tracker to the Simulation study tree.
//  8. Sets the baseline of Trend Tracker to the current results.
//  9. Deletes Pressure-1.
// 10. Meshes the model and analyzes the study.
// 11. Appends new results to Trend Tracker.
// 12. Inspect Trend Tracker (-Iteration 2-) to verify that the Simulation study
//     tree contains:
//     * Trend Journal
//     * Mass1
//     * Stress1
//     * Displacement1
// NOTE: Because the model is used elsewhere, do not save changes.
