Motion: CAD-independent Motion Modeling

Work with Motion data independent from design data

• Motion models no longer require a master part file

• Create simple geometries directly within the Motion application

• Motion-based geometries can be saved in the Motion file directly, no associated part files required

• Associate CAD geometry to the motion model later


Motion: Analytical Contact

Compute 3D contact faster and with smoother contact force results

• Does not require CAD geometry

• Formulations based on basic shapes (spheres, extruded and revolved geometries)

1 Solid-Solid contact

1 AnalyticalSphere-Extrusion

Result & Gain

CPU: 36 sec CPU: 1 sec Fast; no peak due to facetization of CAD geometry

Pin contact right after the slot bend


Motion: Text-based Modeling

Perform motion simulation without the need for Simcenter 3D Motion interface

• Based on Motion Definition File (MDF) – XML format

• Extensibility to add motion elements for vertical applications

• Perform automated computations thanks to standalone Solver and Result Viewer


Acoustic Transfer Vector (ATVs)

Efficiently analyze large models for many frequencies or rotational speeds

• A simplified representation of an acoustic fluid that interacts by weak coupling of a vibrating structure

• For fast radiation noise prediction


Acoustic FEM Adaptive Order (FEMAO)

More accurate and faster solutions for acoustic and vibro-acoustic analyses

• Finite Element Method Adaptive Order (FEMAO) is a higher-order polynomial technique

• Adjusts the element order (shape functions) automatically to ensure greater accuracy

• Faster mesh creation, and easier preprocessing
