Comet/Structural Dynamics

Product logo

Now you can easily and quickly conduct linear FEA, rigid and flexible multi-body dynamic (MBD) simulations with full associativity in a single user environment. What's more, you can conduct these analyses early in the product development process, when simulation can have the greatest impact on product design and quality. Comet/Structural Dynamics enables you to simulate the performance of structures and mechanisms - both static and dynamic - using MBD codes in concert with finite element analysis.

Comet/Structural Dynamics enables you to work with your choice of CAD and CAE applications from multiple vendors - without translations and without having to build and maintain subroutines and linkages to pass data back and forth between systems. These tedious, time-consuming, and error-prone activities are eliminated with Comet/StructuralDynamics. You'll work with a single model in a single environment.

For example, if you use Pro/ENGINEER for design, ADAMS for multi-body dynamics, and ANSYS, ABAQUS, or MSC.Nastran for Finite Element Analysis, your workgroup faces at least three different software environments. Even if you have expert users for each of these systems, valuable time is wasted moving data back and forth, creating and recreating models for each simulation and iteration. It's not only a manual, error-prone process, it also limits the use and impact of product simulation.

With Comet/StructuralDynamics, you only need to build and maintain a single project, which streamlines your process and eliminates errors. For example, changes made to the model in the Pro/ENGINEER CAD mode are fully associative to the MSC Nastran analysis model - and vice versa. You can even automate simulation tasks and capture procedures and best practices, empowering a designer (instead of an expert analyst) to run analyses.

Comet/StructuralDynamics automates the process of creating flexible bodies for MBD simulation and analysis. For example, when working in the Comet environment, your FEA code automatically generates the files required by the MBD solver for a motion simulation study. Comet/StructuralDynamics automates the simulation loop across these codes and automates the FEA simulation process to drive the MBD study.

Comet/StructuralDynamics enables you to begin work on simulations even before geometry is created. You can specify analysis data such as properties for mesh refinement, materials, springs or dampers, boundary conditions and loads, and analysis controls.
