OERSTED
Reducing a company’s design and manufacturing overhead is key to staying on top in today’s competitive
market. OERSTED, a 2D/RS time-harmonic eddy current field solver from Integrated Engineering Software,
delivers the power and performance needed to accomplish this goal, including transients solving. Using
our innovative Boundary Element Method (BEM) technology with the Finite Element Method (FEM) and
Hybrid solvers, 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 is an easy-to-use 2D/RS eddy current field solver for applications like:
- MRI
- Non-destructive testing systems
- Bus bars, charging fixtures
- Induction heating coils
- Magnetic recording heads
- Magnetic shielding
- Coils and transformers
- Induction motors
Fast and accurate, OERSTED calculates force, torque, displacement current, flux linkage,
induced voltage, power and impedance.
Our powerful parametric solvers allow designers to automatically vary and experiment with geometry, materials and
sources – reducing the tedious, repetitive task of fine–tuning multiple design parameters.
For multiphysics analysis, couple OERSTED with
KELVIN, a 2D thermal analysis program.

Step 1 Step 2 Step 3
Create a physical model Obtain a field solution Analyze the solved model
OERSTED reduces design time while improving product performance by letting you design via computer
simulations thereby reducing costs and risks associated with physical prototyping.
Easy-to-learn, OERSTED lets you focus on product development, not software training.
