LF Frequency Domain Solver Overview

The LF frequency domain solver can be used to solve electromagnetic field problems in the low frequency domain. The main task for the solver is to calculate electromagnetic fields and the resulting current densities, losses and energies. These results appear automatically in the navigation tree after the solver run.

Equation types

Three equation types can be solved with the LF frequency domain solver. You can choose between the following options:

Magnetoquasistatic (MQS)
Electroquasistatic (EQS)
Fullwave

Solver specific sources

Different types of sources are available for the three equation types.

Open boundaries

Currently the LF frequency domain solver does not support open boundaries.

Lumped Network Elements

Use lumped elements to include electrical component into the simulation. RLC-Serial and RLC-Parallel circuits are supported by the solvers (currently MQS, Fullwave).

Mesh Type

The magnetoquasistatic and fullwave equation types supports tetrahedral as well as hexahedral meshes. The electroquasistatic solver supports only tetrahedral meshes.

General Hints

Please consider the following general hints on how to increase the performance of your simulation runs.

Always make use of geometric symmetry planes if possible.
Avoid an unnecessarily large calculation domain size.

Result Data Caching

For further processing of single runs within a multi-run (e.g. Parameter Sweep, Optimization) all models and results can be stored in sub-folders on the hard disk when checking the ”Store results in data cache” option. This might be very helpful for own macros or just to check a single run.

Adaptive Mesh Refinement

For all solvers an adaptive mesh refinement can be activated. Therefore the mesh will be refined until the change of the results from one pass to the other deviate less than the given limit in percent. This option produces very good simulation results without the need for manual mesh tuning.
