BEM-FEM Sensors

Finding the best solver for your sensor application

BEM-FEM-Comparison (Left) Permanent Magnet and Pole Piece modeled using BEM. No artificial boundary box
or meshing of open regions is required.
(Right) Permanent Magnet and Pole Piece modeled using FEM. A boundary box to limit the
model space is required, as is meshing of the entire simulation space.

INTEGRATED provides sensor designers with the best solver for their particular applications.

The most common sensor applications can be analyzed with either the Boundary Element Method (BEM) or the Finite Element Method (FEM).

BEM is often the preferred method since many sensor applications involve both large regions of open space and small airgaps. BEM requires neither artificial boundaries to limit the model space, nor meshing of empty space regions.

FEM is particularly well suited to transient simulations which involve the field solution at a large number of time steps.

An additional advantage to having both solution methods is the ability to confirm the validity of models using two independent solvers based on entirely different mathematical formulations.
