Optimisation of Synchronous Reluctance Motors (SynchRels) using Opera


In the last few decades, the synchronous reluctance motor (SynchRel) has been relatively neglected in industrial, domestic and traction application because of the ascendency of permanent magnet (PM) and the ubiquitous induction (IM) motor. Recent volatility in rare earth PM prices and the unavoidable losses in IM’s have renewed interest in SynchRels – especially for [...]


NDT Device Design


Non-destructive testing or evaluation (NDT or NDE) is a process used in industry to evaluate properties of a material or a system without damaging it. Some of the uses of NDT are flaw detection and evaluation, leak detection, location determination, dimensional measurements, structure and Microstructure characterization, estimation of mechanical and physical properties, stress (strain) and [...]


MRI shielding webinar


In this webinar, we show the benefits Opera Optimizer offers when used in conjunction with magnetostatic analysis for MRI shielding applications. We also demonstrate the benefits of the new “thin plate” boundary condition, which increases efficiency without compromising accuracy, and how Opera provides the ability for shielded room designers to customize the Modeller and Post-processor [...]


EUGM 2017: Opera Update 2017


Presenter: Eddie Moor, Programme Manager, Cobham Technical Services Abstract: In this session the Opera Programme Manager will outline key updates in Opera. This will include an overview of recent and future developments as well as a sneak peek at some of the longer term projects for the Opera Roadmap, allowing users the opportunity to give [...]


How to design a linear machine


In this blog I will take a look at the design of linear machines, where advanced material models are being used in order to investigate the effects of hysteresis on the machine characteristic. Linear machines are electrical motors or generators which transform mechanical energy into electrical energy and vice versa, through the use of linear [...]


Electro-mechanical System Analysis using Opera and RomaxDesigner


Presenter: Dr. Melanie Michon, Romax Technology Abstract: The design of integrated electrified drivelines requires a holistic electro-mechanical approach. However, often electrical and mechanical components are designed separately, and problems don’t occur until the complete system is assembled and tested. In particular NVH problems are often caused by interactions between the electrical and the mechanical sub-systems [...]


How to simulate industrial designs for multi-physics applications


Opera is a suite of multi-physics analysis programs that includes electromagnetics, stress and thermal analysis. To highlight the main points that make it suitable for industrial designs: Opera includes an easy-to-use 3D Modeller, allowing models to be created or imported -in a wide variety of standard CAD formats; Scripting in the Modeller makes it a [...]


Simulation of the H-injection system for the CERN Proton Synchrotron Booster in Opera-3d


Presenter: Jonathan Speed, CERN Abstract: The simulation of magnets for CERN particle accelerators is an essential part of the design process of new units, the analysis of the functionality of old ones, and even to guide the identification of magnet faults. One such application is the analysis of the future H- injection system for the [...]


EUGM 2017: Training on modelling & meshing in Opera-3d including interoperability


Presenter: Applications Engineer, Cobham Technical Services Abstract: In this presentation we will concentrate on demonstrating some of the new features that were introduced in latest releases of Opera and on showing some solutions to the problems that originated from enquiries by Opera users and which could be of interest to a wider audience. The geometric [...]


EUGM 2017: Using Python to provide multi-physics capabilities


Presenter: Chris Riley, Engineering Manager, Cobham Technical Services Abstract: Python has been integrated into the Opera-3d solvers in order to allow data calculated during a particular simulation process to be made available to other Opera-3d simulations. For example, force densities at each output time, or indeed time-step, of a transient electromagnetic simulation could be made [...]
