Cobham Technical Services announces the release of a new version of its Opera electromagnetics and multiphysics design software that enables design engineers to considerably accelerate analysis time. 

Design engineers can significantly reduce computational time using Opera-3d version 16 by harnessing the parallel processing capabilities of multi-core processors.

Designed for use on standard office-grade PCs, the latest version of the Opera electromagnetic design software contains numerous enhancements to take advantage of the multi-core processor architecture present in today’s computers. One of the advanced features in Opera-3d is the extremely accurate method used to represent coils, which is widely used by scientists and engineers to model complex devices with up to several hundred coils. The run-time of such complex simulations can be speeded up with the new Opera version.

Opera version 16 further extends the multiphysics capabilities of Opera-3d. Electromagnetic, thermal and stress analysis simulation now operate seamlessly, enabling results from one type of simulation to automatically pass to other simulation types. Users can set up a chain of analyses of the same model and solve them sequentially. Shape deformation caused by forces acting on a model can be employed across different types of simulation; the deformed mesh from stress analysis can be nominated for use in subsequent electromagnetic or thermal analyses.

The Opera-2d circuit editor has been extended to include additional functional components. Capacitors and inductors can be defined as fixed components or as functions of any parameter used in the simulation.

A new dynamic graphing facility that enables users to generate graphs quickly and easily and with greater control over format and content, has been added to Version 16 of Opera-2d and -3d. 

Key features of Opera-3d also include a new tool for simulating magnetron sputtering and thin-film coating, and a volume plasma emitter. While the magnetron sputtering module can be used to analyse target erosion and utilisation, predict substrate coating profiles and evaluate the dynamics of the coating process, the volume plasma emitter captures the behaviour of low density magnetised plasmas.
