Create Nonlinear Study and Apply Materials Example (VBA)

This example shows how to create a nonlinear study and apply user-defined and SolidWorks materials to an assembly's components.


' 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. Run the macro.


' Postconditions:

' 1. Assembly opened.

' 2. A nonlinear study created.

' 3. User-defined material applied to the first component, and

'    SolidWorks material applied to the remaining components.

' 4. To verify, expand the Parts folder in the Simulation Study tree,

'    which is located beneath the FeatureManager design tree, and

'    observe the names of the materials applied to Holder-1 and Pipe-1.


' NOTE: Because the assembly document is used with

' a SolidWorks Simulation online tutorial, do not save any

' changes when closing the document.
