Templates for real parts
Solenoid actuators, conductive plates with holes, shields and coils over conductors.
3D low-frequency fields, without a workstation.
Actuators, solenoids, 3D eddy currents and shields, solved on our servers and viewed in your browser.
What does the 3D Low-frequency Fields do?
The 3D Low-frequency Fields module solves magnetostatic and eddy-current problems in full 3D with the finite-element method. It is meant for geometry a 2D cut cannot represent: actuators and solenoids with plungers, eddy currents in plates with holes, and shields with openings. Every quality runs as a background job on our servers, with a fast preview, and the solver is checked against the international TEAM Problem 7 eddy-current benchmark.
Features
3D eddy currents
Time-harmonic eddy currents in conductors with full 3D current paths.
Benchmarked
Validated against the TEAM Problem 7 asymmetrical conductor benchmark published by the Compumag society.
Server-side solving
Heavy meshes run on our servers as jobs; your laptop only shows the result.
Limits
Quasi-static (low-frequency) physics only. Very fine meshes are queued one job at a time per user.
Every module ships with reference cases that run in our CI. See validation for how results are checked.

Frequently asked questions
What is TEAM Problem 7?
TEAM Problem 7 is a standard eddy-current benchmark: an aluminium plate with an off-centre hole under a racetrack coil, with measured field values. AirInduct Sim's 3D solver is checked against it.
Do I need a powerful computer?
No. 3D solves run on AirInduct Sim's servers; the browser only displays the result.
