Creo Elements/Direct Advanced Simulation

Advanced Simulation Software for Product Design Verification and Validation

Creo Elements/Direct Advanced Simulation Extension software provides a complete set of advanced capabilities for improving your company’s product design verification and validation processes. The software enables you to study in greater depth how advanced, nonlinear effects could influence the performance of your products in development. This allows your design and engineering team to achieve greater insight and fully evaluate product performance early in the development cycle.

The combination of Creo Simulate and PTC Creo Advanced Simulation Extension can be used as a standalone application or as an extension of Creo Elements Direct. Results include streamlined processes, reduced need for physical prototypes, lower costs, as well as greater product quality, safety and reliability.

Benefits

  • Solve nonlinear large displacement, pre-stress, dynamic and transient thermal analyses
  • Simulate advanced materials behaviors such as hyper-elasticity, anisotropic, orthotropic and composite laminates
  • Support for advanced modeling entities such as mass/spring idealizations, pre-loaded bolts and friction on assembly contact points Leverage the familiar interface, workflows and user concepts found in the core design areas of Creo Parametric
  • Optimize product performance and reliability, reducing risk of failure by accurately simulating complex systems under real-world conditions
