ESI Pro-SiVIC 2016 models how sensors perceive scenes and smart products make decisions

New tools for development of Advanced Driver Assistance Systems (ADAS) and autonomous (self-driving) vehicles are highlights of Pro-SiVIC 2016, ESI Group’s latest release of the sensor simulation platform it acquired last year along with the software’s developer, CIVITEC.

Targeted primarily at transportation industries, ESI Pro-SiVIC lets engineering organizations virtually test the operational performance of the various perception systems on board a ground vehicle or aircraft design. By helping engineers build realistic, real-life 3D scenarios and experience them interactively in real time, Pro-SiVIC is intended to reduce or eliminate the need for physical prototypes. The software models environmental factors that influence sensor performance such as lighting conditions, weather, and other vehicles sharing the road. The goal is to let users quickly and precisely study the performance of embedded systems in both typical and critical use cases, to ensure the product will be safe and reliable in operation.

Part of the recent agreement between ANSYS and General Electric expands GE’s use of ANSYS engineering simulation solutions to accommodate GE’s 2015 acquisition of Alstom’s Power and Grid businesses. But of broader import is what the deal will do to extend simulation beyond product development into operations—a key aspect of Predix, the new “Industrial Internet platform” from GE. Predix is an operating system and platform for building applications that connect to industrial assets, collect and analyze data, and deliver real-time insights for optimizing industrial infrastructure and operations.

Using Industrial IoT data to drive optimization

“The age of ‘Big Data’ is here: data of unprecedented size is becoming ubiquitous, which brings new challenges and new opportunities,” observed Peter Richtárik of the University of Edinburgh’s School of Mathematics and Zheng Qu of the University of Hong Kong. “With this comes the need to solve optimization problems of unprecedented sizes.”

The two Big Data experts, organizers of an “Optimization and Big Data 2015” workshop, continued by writing: “Machine learning, compressed sensing, social network science and computational biology are some of many prominent application domains where it is increasingly common to formulate and solve optimization problems with billions of variables.”

In the engineering of discretely manufactured products, few topics today are more ubiquitous than how to prepare for the age of the Industrial Internet of Things (IIoT) and Industry 4.0. The largest effects of these developments, most centrally the resulting tsunami of data about product performance in service, have yet to hit. But when they do, the impact—and opportunity—for both users and developers of design space exploration and design optimization technologies could be transformative. Continue reading

FeatureScript amps up power of Onshape

Full-cloud CAD pioneer Onshape amped up the power and utility of its software with FeatureScript, a new programming language that lets users create new parametric features that look, feel and behave just like Onshape’s built-in features.

This is the same language used by Onshape itself to develop all of its software’s current features—Extrude, Fillet, Shell, Loft and the like. Now available as an open language, FeatureScript lets users create their own built-in parametric features in Onshape.

Under the open-source MIT License, Onshape is also sharing the FeatureScript source code for all of its own features, allowing customers to copy, modify or adapt them as they see fit. New features can be created, and existing features edited, in Onshape’s new Feature Studio, a user-friendly development environment with an editor, in-line help and documentation. Continue reading

Noesis Solutions High-Performance Computing for Surf Bums webinar

Noesis Solutions High-Performance Computing for Surf Bums webinar, August 31, 4:00 am, 9:00 am & 2:00 pm ET. Webinar attendees will learn how to: (1) create an easy-to-use custom application within a familiar tool like Microsoft Excel that makes the magical world of simulation easily accessible to non-specialists for the design of surf boards. Through this application, they will have access to a full range of advanced modeling and simulation tools (Sculptor, OpenFOAM, ParaView & Optimus) and will be able to run them within the scope that the specialist defines within his custom application; (2) hide all the engineering complexity from the target user, but provide him with a full range of reporting tools within Microsoft Excel such that it becomes clear at first glance how the surf board design can be improved and optimized; (3) speed up simulation throughput by connecting the application to the full power of the Microsoft Azure Cloud Computing Platform—all of this completely transparent to the user.
