Feen in a Nutshell
APPLICATIONS

APPLICATIONS

As FEEN is a very general tool, a wide variety of electromagnetic applications can be simulated for different markets. The spectrum ranges from machines and actuators to high-voltage technology, automotive and aerospace. We have prepared some examples for you.

FEEN IN ACTION

THE FEEN
TECHNOLOGY

Electric analysis

Solve electric approximations of
Maxwell equations: DC conduction, electrostatics, as well as time-harmonic and timedomain electro-quasistatics. These analysis types are ideal for many low frequency applications including bus bars, HV devices, insulation co-ordination, Joule heating, IR drop, electric sensors, and switchgears.

Magnetic analysis

All relevant magnetic approximations of Maxwell’s equations can be solved: magnetostatics, time-harmonic as well as time-domain magnetoquasistatics (harmonic and transient eddy currents). This makes FEEN well-suited for a wide range of applications such as motors, generators, transformers, actuators, solenoids, induction heating, magnetic sensors and wireless power transfer.

Upcoming: full Maxwell analysis

FEEN will support the Time Harmonic Full Maxwell Equations, offering RF Analysis for high frequency and resonating structures. This feature is tailored for applications such as antennas, filters, resonators, waveguides, radar cross-section (RCS), RF electromagnetic compatibility (EMC) and interference (EMI), RFID, and NFC technologies.

Fully parallelized

Compute-intensive tasks — such as (non-)linear systems solving, matrix assembly, pre- and post-processing — are distributed across any number of cores. Our implementation exhibits nearly optimal scaling with respect to core count, dramatically reducing computation time and enhancing productivity.  

High-order discretization

First, second and higher order \({\small{\mathrm{H}}^1} \)- and \(\small{\mathrm{H}}(\mathrm{curl})\) conforming finite element discretizations are supported. This capability is particularly advantageous when high accuracy is essential, especially for locally resolving fields with precision, ensuring detailed and accurate simulations.  

Tetrahedral & Cartesian meshes

Classical consistent tetrahedral meshes (plane and curved) are supported as well as Cartesian meshes with hanging nodes. The latter are preferable for very complex geometries and require less CAD-clean up effort. Hanging nodes allow truly localized refinements, e.g. to efficiently resolve air gaps and tiny features, where standard Cartesian meshes fail.   

Advanced multigrid pre-conditioners

FEEN combines Krylov subspace methods with multigrid preconditioners, recognized as among the fastest solution methods for linear systems. This approach ensures quasilinear scaling relative to problem size, enabling efficient simulation of extensive models, including those with tens of millions of cells.   

Periodic boundary conditions

Use cylindrical and translational periodic, antiperiodic and symmetry boundary conditions to drastically reduce simulation time for inherently periodic or symmetric models such as motors or generators.  

Unique sliding mesh technology

Rotational and translational movements can be simulated without re-meshing, even for second order and higher order approximations. This not only accelerates simulations but also enhances robustness, bypassing the complexities associated with external meshers.  

Cloud-friendly

Tap into the immense power of cloud computing for considerable time savings. FEEN is expertly optimized for cloud hardware, streamlining the transition of your application to the cloud and effortlessly overcoming the limitations of on-site hardware.
