Add Elastic Support Fixture Example (VBA)

This example shows how to add an elastic support fixture to a frequency 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 type library as a reference (in the IDE,
'    click Tools > References > SOLIDWORKS Simulation version type library).
' 3. Ensure that the specified model document exists.
' 4. Open an Immediate window.
' Postconditions:
' 1. Opens the model.
' 2. Gets the Ready frequency study.
' 3. Deletes Fixture-1 from Ready.
' 4. Adds an Elastic Support-1 fixture to Ready.
' 5. Prints the properties of Elastic Support-1 to the Immediate window.
' 6. Meshes the model.
' 7. Analyzes Ready.
' 8. Prints the resonant frequency of each mode to the Immediate window.
' 9. Inspect the Immediate window, the Simulation Study tree, and the
'    graphics area.
' NOTE: Because the model is used elsewhere, do not save changes.
