Get Options of Nonlinear Study Example (VB.NET)

This example shows how to get the properties of nonlinear studies.

'---------------------------------------------------------------------------
' 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 file exists.
' 4. Open the Immediate window.
'
' Postconditions:
' 1. Gets the properties of each nonlinear study.
' 2. Modifies the step/tolerance options in each nonlinear study.
' 3. Prints the properties of each nonlinear study in the model to the
'    Immediate window.
'
' NOTE: Because the model is used elsewhere, do not save any changes.
