Create Nonlinear Study and Apply Materials Example (VB.NET)

This example shows how to create a nonlinear study and apply user-defined and SOLIDWORKS materials to assembly components.

'----------------------------------------------------------------------------

' Preconditions:

' 1. Add the SOLIDWORKS Simulation as an add-in

'    (in SOLIDWORKS, click Tools > Add-ins > SOLIDWORKS Simulation).

' 2. Add the SOLIDWORKS Simulation primary interop assembly as

'    a reference (in the IDE's Project Explorer, right-click

'    the project name, select Add Reference, click the Browse tab,

'    navigate to the install_dir\api\redist\CLR2 folder and

'    select SolidWorks.Interop.cosworks.dll).

' 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.
