Lotus thrusts out CAE packages

Latest version of Lotus Engineering’s PC-based CAE (computer aided engineering) software packages, now on general release, include better compatibility with the increasingly popular Simulink modelling and control system development environment. The firm’s tools have been developed in anger on its own powertrain and vehicle development projects for clients around the world. Indeed, it’s interest from those clients wanting the software that initially prompted Lotus to set up a separate division to take it to market. Clients already include Tier One automotive suppliers, vehicle OEMs and motor racing companies as well as universities and research facilities. Lotus Engineering designed engines like the Opel Family One and GM L850 global engines; and on the vehicle side, it’s been involved with the development of the Aston Martin V12 Vanquish, the Lotus Elise and the Opel Speedster/Vauxhall VX220. “It is precisely because we use the software extensively within our own internal and client projects, and because we work closely with our software clients, that we are able to continuously improve and evolve the packages,” says Nigel Fleming, head of Lotus Engineering Software. “The latest releases are designed to combine a fully capable, integrated simulation environment with an intuitive and user-friendly interface. This enables rapid familiarisation, allowing engineers to get up to speed faster and achieve greater productivity.” Simulink connections mean complex controls can now be incorporated right into the mechanical computer models, extending the power of the simulation environment. There are three systems. Lotus Engine Simulation is for performance prediction, now being used in conjunction with Lotus’ advanced AVT system for powertrain research. Lotus Vehicle Simulation is for virtual vehicle building and performance analysis, including of exhaust emissions and fuel consumption. And Lotus Concept Valve Train then covers kinematic performance analysis of valve actuation mechanisms.
