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
> 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. Applies user-defined material to the first assembly
component
// and
SOLIDWORKS material 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 elsewhere, do not save
changes.
