NumaPowerGenerator Module

Produces libnuma-powergenerator.so module. This module is used to approximate the behaviour of an radiofrequency ablation power generator, which takes readings from several thermocouples and distributes power to a series of tines, spreading out from the end of a percutaneous needle.

NumaPowerGeneratorSolver

Updates the power field based on the present phase. If the phase changes, the distribution field profile is recalculated. If the power is negative, the simulation gracefully exits. If the overall input power is controlled by a PID controller, this is also taken into account and calculated. Output variables are Electric Distribution (normalized field), ObservedTemperature (from the thermocouples), Impedance (FIXME: requires work), Applied Power (post-PID total output) and Phase. All but the first are global (0D) variables.
