Create Trend Tracker Example (VBA)

This example shows how to create a Trend Tracker for a static 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. Copy public_documents\samples\tutorial\api\tjoint.sldprt to another name and replace
'    file_name in the code with the new name.
' 4. Open the Immediate window.
'
' Postconditions:
'  1. Opens the model document.
'  2. Gets the static study.
'  3. Meshes the model.
'  4. Sets the solver type.
'  5. Analyzes the study.
'  6. Click Yes if asked to save the model.
'  7. Adds Trend Tracker to the Simulation study tree.
'  8. Sets the baseline of Trend Tracker to the current results.
'  9. Deletes Pressure-1.
' 10. Meshes the model and analyzes the study.
' 11. Appends new results to Trend Tracker.
' 12. Inspect Trend Tracker (-Iteration 2-) to verify that the Simulation study
'     tree contains:
'     * Trend Journal
'     * Mass1
'     * Stress1
'     * Displacement1
'
' NOTE: Because the model is used elsewhere, do not save changes.
