System Simulation for Model-driven Automotive Health Monitoring and Predictive Maintenance

Rather than just listing all the new capabilities for system simulation and analysis in the latest release of ANSYS Simplorer, I thought it would be interesting to share a cool example of how our systems capabilities have been applied to health monitoring of an automotive braking system. And along the way, I’ll highlight how the advancements in ANSYS 18 help our customers model and simulate systems such as these.

This example illustrates a physics-based system model intended to support health monitoring and predictive maintenance of automotive braking systems. And while this is an automotive example, our customers throughout different industries are developing similar capabilities to monitor and manage the performance of their products in operation — all in the name of improving safety, performance, and overall customer satisfaction.  Continue reading

Virtual Systems Prototyping with Modelica in ANSYS Simplorer

Last summer, we shared with you some of the advances in ANSYS 16.2 as they related to virtual systems prototyping, including how you can optimize your product development process and improve collaboration among different departments and disciplines. I’m happy to let you know that we’ve continued to enhance our systems offering with the latest release of ANSYS Simplorer in ANSYS 17.0.

ANSYS Simplorer users will be delighted to know that you can create and assemble models faster than ever using Modelica models. Native support for the Modelica language allows you to import Modelica models directly into Simplorer. New library components provide access to hundreds of additional mechanical and fluid component models for complex electrified systems. Continue reading

Expanding System Simulation with Modelica

System Simulation.  It is an activity that can be defined broadly, and for many organizations it represents an aspiration for a type of engineering analysis that spans departments and disciplines and doesn’t fall into the familiar buckets of 3-D structures, fluids and electromagnetics. In contrast to 3-D multiphysics simulation, which seeks to understand coupling effects of different physical phenomena in the detailed design of individual components, multi-domain system simulation is used to analyze the interactions of many components operating together as a system, including software components describing embedded control and user interfaces.
