Granta updates CES Selector software

A Granta Design product story
Edited by the Engineeringtalk editorial team Oct 8, 2008

Granta Design will demonstrate a new version of its CES Selector software at this week's Materials Science and Technology (MSandT) conference in Pittsburgh.

Enhancements to the CES Selector include: a quick and simple method to specify design objectives, an Eco Audit Tool, capabilities for cost analysis, further plastic selection options and extended coverage of medical materials.

CES Selector combines data on the properties of materials with powerful graphical software, developed at Cambridge University and Granta, for analysis and selection.

It enables designers, engineers, and materials experts to explore materials and process options and to make and justify rational, auditable selection and substitution decisions.

The software is valuable in balancing competing engineering, economic, and environmental objectives.

It is now easier to specify design objectives via a new pictorial menu in which engineers view and select the mechanical, thermal, electrical, or barrier application they wish to study.

Simple drop-down lists enable them to choose variables (such as dimensions, cost, strength, or CO2 footprint) to optimise or constrain.

The software then plots graphs that show the best materials for the user's requirements and enable a trade-off of competing objectives.

The new menu makes the software quicker to use in practical design.

Granta is also introducing more flexible site- and company-wide licensing, as well as new training options for the software users.

Another new design feature is the Eco Audit Tool.

A user enters information about a product design's composition, processing, use, transportation and disposal.

The tool combines this with eco property data to estimate the energy usage and CO2 output at each stage in the product's lifecycle.

CES Selector's analysis capabilities can be used to identify materials and process changes that will minimise environmental damage.

The aim is to make such decisions early in the design phase, when they cost the least and have the most effect.

Data modules in the CES Selector contain regularly updated property and processing data about thousands of engineering materials.

New price estimates are available for more than 3,000 materials.

These enable users to rank materials based on cost per unit of function for an engineering application.

New specialist data is also available for medical and food contact applications and for plastics.

The medical data covers issues such as the regulatory approval status of materials and their sterilisability, durability to chemicals and permeability.

This data has been extended to cover not only medical plastics, but also metals and ceramics.

Plastics data now includes more information on important classes including elastomers, rubbers, and transparent plastics.
