This example shows how to create a drop test study.
//----------------------------------------------------------------------------
// Preconditions:
// 1. Open:
// install_dir\samples\tutorial\api\KeyPad_1.sldasm.
// 2. Add the SOLIDWORKS Simulation as an add-in
// (in SOLIDWORKS, click Tools > Add-ins > SOLIDWORKS Simulation).
// 3. Add the SOLIDWORKS Simulation primary interop assembly as
// a reference (in the IDE's Project Explorer, right-click
// the project name, select Add Reference, click the Browse tab,
// navigate to the install_dir\api\redist\CLR2 folder and
// select SolidWorks.Interop.cosworks.dll).
//
// Postconditions:
// 1. Default drop test
study results plot is created.
// 2. Drop test study, "Study 2", is created.
// 3. Nylon 101 SOLIDWORKS material is applied to all components.
// 4. The mesh is created.
// 5. Drop height is set to 1000 mm.
// 6. Analysis is run.
// 7. The von Mises stress results in the last step are validated.
// 8. When the macro stops, inspect the Immediate window for the
// 1000 mm drop test study's setup and result options.
// Inspect the default drop test results plot.
// Click F5 to continue.
// 9. Drop height is changed to 2000 mm.
// 10. Analysis is run again.
// 11. Inspect the results folder.
//
// NOTE: Because the model is used elsewhere,
// do not save changes when closing it.
