Create Nonlinear Study and Apply Materials Example (C#)

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 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 assembly 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.
