Add Elastic Support Fixture Example (VB.NET)
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 primary interop assembly as a reference
' (in the IDE, click Project > Add Reference > .NET >
' SolidWorks.Interop.cosworks > OK).
' 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.
