Surface contact

Autodesk Nastran In-CAD software includes contact modeling options to help you explore more natural interactions between parts, and to help alleviate guesswork on a simplified load or restraint.

The Autodesk Nastran In-CAD solver makes easier work of inherently nonlinear computations. Model press-fits, gears, mechanical components, and assemblies with different kinds of contact—such as sliding, friction, and welding—to produce simulations with real-world fidelity.
