Get Frequencies in Mode Shape Plots Example (VB.NET)

This example shows how to get frequencies for all mode shapes in amplitude plots.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Add the SOLIDWORKS Simulation as an add-in
'    (in SOLIDWORKS, select Tools > Add-ins > SOLIDWORKS Simulation
'    and click OK).
' 2. Add the SOLIDWORKS Simulation primary interop assembly as a reference 
'    (in the IDE's Project Explorer, right-click
'    the project name, click Add Reference, click the Browse tab,
'    navigate to install_dir\api\redist\CLR2
'    click SolidWorks.Interop.cosworks.dll, and click OK).
' 3. Ensure that the specified model exists.
'
' Postconditions:
' 1. Meshes the model.
' 2. Analyzes the study.
' 3. Gets the frequencies of all amplitude plot mode shapes.
' 4. Displays a message box with the frequency for mode shape 2.
' 5. Click OK.
'
' NOTE: Because the model is used elsewhere, do not save changes.
