Add Component Contacts Example (C#)
This example shows how to add component contacts to a frequency study.
//----------------------------------------------------------------------------
// 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. Ensure that the specified material library exists.
// 4. Ensure that the specified model document exists.
// 5. Open the Immediate window.
//
// Postconditions:
// 1. Opens the model.
// 2. Creates Frequency 1 study.
// 3. Uses a soft spring to stabilize the model.
// 4. Adds Component Contact-1 and Component Contact-2 to the
// Component Contacts folder in the Simulation study tree.
// 5. Prints the component contacts' properties to the Immediate window.
// 6. Applies ductile iron to the model.
// 7. Meshes the model.
// 8. Analyzes Frequency 1.
// 9. Prints the resonant frequencies of each mode to the Immediate window.
// 10. Inspect the Immediate window, the Simulation study tree, and the
// graphics area.
//
// NOTE: Because the model is used elsewhere, do not save changes.
