Get Mesh Elements and Nodes Example (C#)

This example shows how to get the elements and nodes of a solid mesh.

//----------------------------------------------------------------------------
// 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. Open public_documents\Simulation Examples\tutor1.sldprt.
// 4. Open the Immediate window.
//
// Postconditions:
// 1. Activates the Ready study.
// 2. Creates a solid mesh.
// 3. Gets the elements and nodes of the solid mesh.
// 4. Gets the elements and nodes at a depth of 0.001m in the solid mesh.
// 5. Runs the study.
// 6. Inspect the Immediate window.
//
// NOTE: Because the model is used elsewhere, do not save changes.
