OPERA SIMULATION SOFTWARE

Opera is able to give accurate numerical solutions to real-world problems in: • • • • • • • Electrostatics Magnetostatics Low frequency electromagnetics High frequency electromagnetics Space charge Thermal problems Structural problems Opera has a wide range of supporting capability to enable high-fidelity models that includes: • • • • • • • • Moving parts Transient fields Non-linear materials Hysteretic magnet materials Lossy dielectrics External circuits System engi

Specialist facilities are offered for examining specific conditions in more detail than might be feasible with standard facilities and solvers, including: • Quench of superconductors • Demagnetization of magnets • Magnetron sputtering Engineering products are becoming more sophisticated and complex, yet development timescales invariably shorten. In today’s global marketplace, competition is becoming more intense. More than ever before, successful products need to be highly optimized for their target markets. This might demand optimization in different forms such as lower raw material costs,...

PRE-PROCESSING FEATURES INCLUDE: • Geometry building • 2d sketching • Non-linear materials • BH curve editor • Library of materials • Circuit Editor • Parameterized conductors • Coupling to systems models • Geometry interfaces include: • Parasolid • SAT • IGES • CATIA • Creo • NX • Solidworks 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...

Interrogate results efficiently Once the simulation is complete Opera’s post-processor simplifies the analysis of the results. As well as displaying the field, temperature or stress, there are numerous functions to prepare and display derived quantities in forms and units familiar to the user (including forces, power loss, stored energy). The post-processor has application-specific capabilities such as being able to compute and display particle trajectories through the computed electric and magnetic fields. POST-PROCESSING FEATURES INCLUDE: • Contours • Vector plots • Graphs • Results on...

Optional modules are available for advanced material modelling: • Lossy dielectrics • Demagnetization of hard magnetic materials • Hysteresis in soft magnetic materials SINGLE PHYSICS OR MULTI-PHYSICS... YOU CHOOSE 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. Static Electromagnetics The Static Electromagnetics module computes magnetostatic and electrostatic fields or DC current flow. The formulation minimises required...

Structural The Stress Analysis Module can be used to perform two different types of solution; Static Linear Stress analysis will calculate displacements, strains and stresses due to external (or internal) forces. Eigenvalue analysis will calculate the eigenmodes and frequencies of a structure in an unloaded state. Thermal The Thermal Analysis Module computes the steady state or transient temperature, heat-flux, and thermal-gradient fields due to electromagnetic heating or external heat sources. Thermal properties, such as the conductivity tensor or specific heat, and heat source density can...

CAPABILITIES: • Self-consistent, relativistic, space charge analysis • Combined electric and magnetic field tracking • Includes beam magnetic field, current flow and dielectric charging • Multiple surface and volume emission models • Primary and secondary emission • Plasma modelling • Fast and accurate SPACE CHARGE Many industrial, medical and scientific products rely on the behaviour of charged particles. Engineers must design systems to precisely control charged particle generation, their manipulation and their interaction with matter and electromagnetic fields. Whatever the application,...

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...

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 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...
