D-Cubed: Latest release of the AEM, Version 41.0

Siemens PLM Software announced the latest release of the D-Cubed Assembly Engineering Manager (AEM), a software component that provides a more realistic and productive assembly environment. New enhancements specific to version 41.0 are listed below. See the full product description.

Reliability enhancement: refined contact algorithms

The AEM simulates the interactions between rigid bodies in motion in assemblies and mechanisms. It uses sophisticated collision detection algorithms to establish contact points between objects, and through its integration with the D-Cubed 3D DCM it resolves the contact constraints that help determine the motion.

When there are multiple touching faces it is likely that the AEM does not need to apply contact constraints to them all. In version 41 the algorithm has been improved to apply contact constraints more selectively, thereby reducing the number of constraints to be solved, and increasing the performance and reliability.

Reliability enhancement: enhanced drag force calculation

The AEM solves a variety of forces between parts in a model in order to help determine the appropriate motion. The drag force is a force applied at a point on a part when a user clicks and drags to interact with the model. In this release the algorithm which determines the appropriate drag force has been improved to ensure that any contacts in the model which need to be removed are done so efficiently.

About the D-Cubed AEM

First released in 2001, the AEM simulates the motion of assemblies and mechanisms. It takes account of the mass properties of parts, the motion caused by a variety of engineering related forces and devices, and the interaction of parts as they collide and push each other around. The AEM is typically integrated at the core of a CAD system and its usage requires no specialist expertise or model preparation.

AboutSiemens PLM Components; Parasolid and D-Cubed

PLM Components are software tools that promote interoperability in CAD, CAM, CAE and PLM applications. Siemens PLM Software develops these components, uses them throughout its own applications and licenses them to independent software vendors and end-user organizations. PLM Components include the Parasolid and D-Cubed products, widely used technologies that provide 3D part and assembly modeling, editing and interoperability, 2D/3D parametric sketching, motion simulation, collision detection, clearance measurement and visualization functionality. Applications include mechanical CAD, CAM, CAE, mold design, sheet metal, AEC, GIS, structural, plant and ship design, CMM, reverse engineering and sales configuration.
