OERSTED two-dimensional electromagnetic eddy current solver
The OERSTED 2D / RS time harmonic eddy current field solver provides the power and performance needed to solve a transient electromagnetic field. Using our innovative Boundary Element Method (BEM) and Finite Element Method (FEM) solvers, OERSTED differs from magnetic design issues in that it requires large open field analysis, accurate boundary modeling and application processing when dealing with small surface depth problems. is crucial. OERSTED provides powerful tools for magnetic field analysis, calculating parameters such as force, torque, induced voltage, displacement current, flux linkage, induced voltage, power, impedance and current.
The powerful parameter solver allows designers to automatically change and experiment with geometry, materials and sources. Since post-processing tools are available in OERSTED, designers can set up calculations and graphical analysis for any parameter without standard output, reducing tedious, repetitive tasks—adjusting multiple design parameters.
main feature
Various applications of magnetostatic/quasi-static/transient two-dimensional and rotationally symmetric eddy current field solvers
The OERSTED package includes:
Choice of solvers: To ensure your confidence in the solution and independent verification, both the boundary element method and the finite element method are included in the same package to meet your specific application needs. Not every solver is suitable for every application, there is no "universal solver".
Choice of optimization tools: Parametric analysis is for those users who need to use short-term learning curves to achieve fast and simple optimization. APIs and scripts give advanced users more privileges. Both tools are included in the same package.
Built-in material libraries: To make it easy for you to access the materials you need to use, you can customize and create your own libraries.
Integration with MATLAB: The user's MATLAB code can call API functions, build geometry, assign physical parameters, solve and get results.
The intuitive interface makes it easier to customize to the user's preferences (overall appearance, toolbar, solver, background, default, etc.).

optimize
In the same package, OERSTED includes various optimization tools so you can find a specific design that works best for you: parametric analysis, scripting, and API.
Parametric analysis is best for users who use short-term learning curves to achieve fast and simple optimization. APIs and scripts give advanced users more privileges.
The parameterization function allows the definition of variable parameters by stepping through multiple "ifs" and facilitating design optimization.
Script: Almost unlimited ability to explore design changes.
API
Create your own application and write specialized tools for specific tasks. When using the OERSTED program in the background, users can program and fully control their custom electromagnetic applications.
OERSTED's API allows for a variety of programs, such as MATLAB, Excel and Microsoft Visual Studio, which work with our software in an interrelated environment. Other software tools can be used in the same way as the API.
Add a utility: Choose our unique custom mini-program to enhance your design capabilities.
Users with programming and/or scripting skills will find this to be a very powerful tool.
