Opera — Electromagnetic and Electromechanical Simulation

Electromagnetic and Electromechanical Simulation

Opera Simulation Software is a software package for finite element analysis in the design of motors, magnets and electrical machines. With low-frequency simulation capabilities, high fidelity, dedicated 2D/3D pre- and post-processing environments, a GUI specifically designed for electromagnetism and multiphysics design, programming regular actions into parameterized macro files, and customization, Opera is used in a wide range of applications in various industries. It could be, for example:

With a set of specialized interfaces and advanced material modeling capabilities, users can solve these and other complex problems much faster and with better results.

Include Modules

Opera has been developed with a number of physics solvers. Each branch of physics has been developed to offer accurate and efficient solutions. Transfer of results quantities between physics can be automated and chained.

Build simulation models quickly

Components and assemblies can be imported from an existing CAD system or alternatively be created using Opera’s built-in modeller with its powerful ACIS geometry kernel. A key feature of Opera is its ability to define any dimension of a model as a parameter, allowing the user to perform ‘what-if?’ investigations and optimize the design model. The Opera model file contains a complete history of the commands that created the database enabling files to be ‘replayed’ and modified – this then delivers a template that is able to automate the design variations of standard products.

    Magnets

    High performance magnets play an important role in science, medicine and industry. Magnet designs are often made for a relatively low number of installations and re-design of tooling required for manufacture must be minimized. Material costs are also often very high. These characteristics mean that prototyping is both time consuming and expensive. Opera provides the software tools to give confidence that designs are right first time by giving the designer the ability to create virtual prototypes that can be relied on. In most applications, the quality of the magnetic field is the important criterion for an optimized design.

    Capabilities

    • Parameterized pre-formed coil shapes;
    • High precision field calculations;
    • Magnetic field can be used to steer and focus a charged particle beam;
    • Charged particle tracking can be performed to determine the beam path through individual magnets or multi-magnet systems;
    • Losses and forces can be automatically transferred to Opera’s multiphysics simulations and their effect on electromagnetic performance can be readily assessed;
    • The effect of the inductance and resistance of the magnet on AC and transient performance can be analysed by coupling the winding to its power supply circuit Superconducting quench can also be modelled.

    Electrical Machines

    The current demands for high efficiency, reliability and low cost of electrical machines require the use of extremely accurate and integrated simulation tools. Whether designing a motor or a generator, an axial or radial flux topology, rotating or linear motion, Opera provides the right tools for the task. Opera integrated multi-physics capabilities allow for a complete machine characterisation using a multidisciplinary approach. A powerful scripting language allows for rapid prototyping and optimization, while the integrated Machines Environment gives users the possibility to quickly and easily setup their customised machine designs.

    Capabilities

    • Motional solvers including mechanical coupling and coupled electrical circuit;
    • Power supply control including soft, swtiching, PWM, current and position feedback;
    • Modelling of skewed structures within motional solvers;
    • Eccentricities and fault operation;
    • Demagnetization of permanent magnets;
    • Loss calculation including hysteresis effects.
