OERSTED ——二维电磁涡流求解器

OERSTED 2D / RS时间谐波涡流场求解器,提供完成瞬态电磁场的求解所需的功率和性能。利用我们创新的边界元法(BEM)与有限元法(FEM)求解器,OERSTED区别于磁设计问题,需要大的开放场分析, 精确的边界建模和应用程序在处理小的表面深度问题时是至关重要的。 OERSTED为磁场分析提供强大的工具,计算所得的参数,如力、力矩、感应电压,位移电流、磁链、感应电压、功率、阻抗和电流。

强大的参数求解器允许设计师自动变化和利用几何,材料和来源做实验。由于在OERSTED中可以使用后期处理工具,所以设计者可以为没有标准输出的任何参数设置计算和图形分析,减少繁琐的,重复的任务-调整多个设计参数。

OERSTED, a 2D/RS time-harmonic eddy current field solver from INTEGRATED Engineering Software, delivers the power and performance needed to accomplish transient EM field solving. Using our innovative Boundary Element Method (BEM) technology with the Finite Element Method (FEM) solver, OERSTED distinguishes itself in magnetic design problems that require large open field analysis, exact modeling of boundaries and in applications where dealing with small skin depths are critical.

OERSTED provides powerful tools for magnetic field analysis, and calculation of resultant parameters such as force, torque, induced voltages, displacement current, flux linkage, induced voltage, power, impedance and currents.

Our powerful parametric solvers allow designers to automatically vary and experiment with geometry, materials and sources. Thanks to the post processing tools available in OERSTED, designers can set up calculations and graphical analysis for any parameters not available as standard output – reducing the tedious, repetitive task of fine–tuning multiple design parameters.

Key Features

·        Magnetostatic/Quasi-static/transient 2D and rotationally symmetric eddy current field solver for a diverse range of applications

·        At no extra cost, our software packages include:

·        Choice of solvers: To ensure you have confidence in the solution and for independent verification, both BEM and FEM methods are included in the same software package to suit your specific application needs. Not every solver fits every application, no “one size fits all”.

·        Choice of optimization tools: Parametric Analysis for those who need fast and easy optimization with a short learning curve. API and Scripting give more power to advanced users. Both tools are available in the same package.

·        Built-in material libraries: Customize and create your own library for easy access to the materials you use.

·        Integration with MATLAB?: Users’ MATLAB code can include function calls to the INTEGRATED API to build geometry, assign physical parameters, solve, and obtain results.

·        Parallelization: When used on 64-bit computers, this permits full utilization of the available RAM to dramatically increase speed of solution and post-processing.

·        Intuitive interface that can be easily customized according to user preferences (overall appearance, toolbars, solvers, backgrounds, defaults, etc).

·        Auto solver will choose FEM or BEM based on the general nature of a model (either can still be manually selected).

·        Self-adaptive meshing and optional user refinement.

·        User assigned weighting factors: Inform the solver of areas that interest you so the that the local results are refined.

·        Periodic and symmetry features minimize modeling and solution time.

Optimization

·        At no extra cost, INTEGRATED includes a variety of optimization tools in the same software package so that you can find one that best suits your particular design: Parametric Analysis, Scripting and API. Parametric Analysis works best for those who need fast and easy optimization with a short learning curve while API and scripting give more power to advanced users.

·         

·        The parametric feature allows a definition of variable parameters to be stepped through for the analysis of multiple “what-if” scenarios and facilitating design optimization.

·        Scripting: Virtually unlimited ability to explore design variations.

API

·        Create your own applications: Write your own dedicated tools for specific tasks. Users can program and have full control of their custom electromagnetic application, while using INTEGRATED programs in the background.

·        INTEGRATED’s API allows a variety of programs such as MATLAB, Excel, and Microsoft Visual Studio to work with our software in an interconnected environment. Other software tools can be used with our API in the same way.
