6.25.6 Global Energy Probes
Global energy probes take integrated energy measurements over the entire simulation
space. The format is simply:
energy TYPE
where ‘TYPE’ is one of the types from the table below. The available types are:
field_flux:
Instantaneous energy flux (rate) into the system through the fields at outlet
boundaries.
particle_flux:
Instantaneous energy flux (rate) into the system through particle creation.
dedx_loss:
Instantaneous energy lost from the system through particle absorption.
field_energy:
Total energy in the system contained in the fields.
particle_energy:
Total energy in the system contained in the particles.
total_energy:
Total energy in the system of both kinds.
net_energy:
Amount of energy in the system which is not accounted for, that is, the total
energy in the system minus the accumulated measurable energy gained by the
system up to the time that this measurement is taken. If there are no other
abnormal means of energy entering or leaving the system, this could be a good
measurement of energy conservation in the field-particle interactions or the
collisional plasma processes.
6.25.7 Global Medium Probes
Global medium probes take integrated measurements over the entire simulation space.
The format is simply:
medium M TYPE
where ‘M’ is the medium index and ‘TYPE’ is one of the types from the table below. The
only available type is:
radiation_energy:
Cumulative energy radiated by Bremsstrahlung production from a method 4
medium model (see Section 6.9.34 [method 4], page 83).
6.25.8 Convergence Probes
Convergence probes are an easy way to gauge how well the simulation is performing
in the various iterative solution techniques available. These include the static electric field
solution, the magnetostatic solution, and any of the implicit solutions. The format is simply:
