How to design for x-ray tube

In this blog we will look at the utility of the Opera simulation environment for the simulation of X‑ray tubes. Firstly, we will concentrate on their operation and design parameters, and the requirements that these place on tools used in their design. We’ll follow this with look at the capability of Opera to meet these [...] Posted in How to...,X-Ray Tubes

How to design for MRI magnets

In this blog we’ll look at the design of shielding for a known MRI magnet, but also at the solution to developing a model of the magnet when only fringe-field maps are available. The basic ground-work of what has become known as MRI was laid in the 1950’s but it wasn’t until the 1970’s that [...] Posted in How to...,Magnets,Magnets Paper,MRI / NMR Magnets

How to design for non-destructive testing equipment

This blog will look at electromagnetic NDT devices, and how simulation can be used in the design process. We’ll start by classifying the sort of NDT problem we will consider and then we will look at the two classes of electromagnetic NDT methods in more detail, both its methodology, and testcases to demonstrate the applicability [...] Posted in How to...,NDT Papers

How to design an induction machine

The Induction Machine (IM) is the most widely used type of electrical machine. By some estimates it accounts for 90% of all small size motors (10 – 750W) and 60 -70% of medium size motors (0.75 – 375 kW). This is mainly due to their reliability, low cost and wide range of torque / speed [...] Posted in How to...,Induction Machines,Motors

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 [...] Posted in How to...,Linear Motion,Motors,Motors Papers

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 [...] Posted in Charged Particle Devices,CPD Papers,How to...,Induction Welding

How to simulate magnetron sputtering

By Nigel Atkinson So, what is magnetron sputtering? It is a physical vapour deposition technique, in which a plasma in a chamber is used to generate ions that are accelerated towards a negative target, ejecting material, which is then allowed to deposit on a workpiece, or substrate as it is usually known. Low pressure is [...] Posted in Charged Particle Devices,How to...

How to simulate transformers

Hello and welcome to this short blog on the simulation of transformers in Opera. Starting with the very basics of transformers, in an ideal world different windings on primary and secondary circuits produce transformed voltages and currents on the output compared to the input according to very simple calculations.

How to simulate superconducting corrector coils in accelerator magnets

By Chris Riley  Welcome to this blog on modelling superconducting corrector coils with OperaFEA simulation software. We will start with a little bit of history.  The Opera software has links back to the Rutherford laboratory’s Computer Applications Group that began developing computer methods for the design of particle accelerator magnets in the late 1960s. The [...] Posted in Accelerator Magnets,Confinement Coils,Gradient Coils,How to...,Superconducting Magnets,Superconductivity Papers
