Apply Material to Bodies Example (C#)

This example shows how to apply user-defined and SOLIDWORKS-defined materials to different bodies.

//---------------------------------------------------------------------------

// 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. Verify that the specified material library exists.

// 4. Verify that the specified assembly exists.

//

// Postconditions:

// 1. Opens the assembly.

// 2. Creates a nonlinear study.

// 3. Gets the number of components.

// 4. Applies materials to all components.

// 5. Expand the Parts folder in the Simulation Study tree

//    to verify step 4.

//

// NOTE: Because this assembly is used elsewhere, do not save changes.
