Solving process (according to the scenario)
Solving process
The last stage is the problem solving process.
The solving process, which depends on the chosen computation type, has got two stages, as presented in the table below.
PEEC computation (independent of the selected application) 


computation of resistances and partial
selfinductances (R, L) for each element of the conductor
mesh, computation of partial mutual inductances (M) among all the parallel elements of the conductor mesh 

Results independent of the frequency 
Supplied conductors Application  Conductors impedance Application 

solving the electric equations ⇒ value of the electric current in each element  reducing the electrical scheme ⇒ value of the equivalent impedance at the level of the impedance probes 
Results depend on the frequency  Results depend on the frequency 
Concept of scenario
The progress of the solving process is set in the software via a scenario. A scenario defines the range of the frequencies for which a Flux PEEC solving process is carried out.
A scenario can be monofrequency (single frequency) or multifrequency (several frequencies). In the second case, the range of frequencies to be considered is divided into intervals, whose definition is described in the following blocks.
Concept of interval
An interval of frequencies is a set of values between a lower limit f_{inf} and upper limit f_{sup}. Moreover, these values can be identified by mathematical laws.
In Flux PEEC two successive intervals must be contiguous, in the sense that the lower limit of the second interval must coincide with the upper limit of the first interval.
There are different ways to describe a range of frequencies, as presented in the table below.
