Since version 2026, Flux 3D and Flux PEEC are no longer available.
Please use SimLab to create a new 3D project or to import an existing Flux 3D project.
Please use SimLab to create a new PEEC project (not possible to import an existing Flux PEEC project).
/!\ Documentation updates are in progress – some mentions of 3D may still appear.
Frequency
Reminder
The Steady State AC Electric application can be used to deal with low frequency problems.
At low frequency, the equations of the electric fields 
and 
and the equations of the
magnetic field 
and
can be
decoupled.
This separation depends on: materials, work frequencies, size of the study domain. This separation is usually regarded as valid for frequencies in the range f < 1 to 10 GHz.
The frequency is defined during the choice of the application.
