Opera Improves Coil Representation

Cobham Technical Services has released a new version of its Opera electromagnetics and multiphysics design software (Opera-3d version 16) that enables design engineers to accelerate analysis time. By

Designed for use on standard office-grade PCs, Opera-3d version 16 contains numerous enhancements to take advantage of multi-core processor architectures, the company says. One of the advanced features is the accurate method it uses to represent coils; the run-time of these simulations can be much faster with the new Opera version, according to Cobham.

The update 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.

Other major features include the addition of a tool for simulating magnetron sputtering and thin-film coating, and a volume plasma emitter. The magnetron sputtering module can be used to analyze target erosion and utilization, predict substrate coating profiles and evaluate the dynamics of the coating process. The volume plasma emitter captures the behavior of low-density magnetized plasmas.
