Convert Study Example (VB.NET)

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.
