Analyze Part Example (VBA)
This example shows how to create a static analysis of a part.
NOTE: To get persistent reference
identifiers (PIDs) for model selections, you can use
pidcollector.exe
or IModelDocExtension::GetPersistReference3.
'---------------------------------------------------------------------------
' This example shows how to create a static analysis of
a part.
'
' Preconditions:
' 1. Add
the SolidWorks Simulation as an add-in
' (in
SolidWorks, click Tools > Add-ins
> SolidWorks Simulation).
' 2. Add
the SolidWorks Simulation type library as a reference
' (in
the IDE, click Tools > References
> SolidWorks
' Simulation
version type
library).
' 3. Modify
the path to solidworks materials.sldmat
if needed.
' 4. Open
the Immediate window.
' 5. Run
the macro.
'
' Postconditions:
' 1. Study
called Static-solid is created.
' 2. Material
is applied to the model.
' 3. Restraints
and pressure are applied to the selected faces.
' 4. Mesh
is created.
' 5. Analysis
is run.
' 6. Strain
and stress results are written to the Immediate window.
'
' NOTE: Because the part document is used by an online
' SolidWorks Simulation tutorial, do not save any changes
' when closing the document.
