This macro file defines the macros for setting up and writing physics-set-flux emitters into particle species definition.

Public Macros

addPhysicsSetFluxEmitterSource(sourceName, sourceKind, owningSpecies, start, stop, vbar, vsig, workFunc, fldEvalOff, temp, fldEnhance, fluxMult, A, B, Cv, Cy, emOff, maskFunction, object, location)

Adds a particle emitter source to a particle species. This macro handles the case of emission from a shape geometry.

Parameters

  • sourceName – The name of the source block.

  • sourceKind – The kind of emission model being used.

  • owningSpecies – The name of the species that contains this source block.

  • star – Time to start emission.

  • stop – Time to end emission.

  • vbar – The mean velocity of the distribution of emitted particles.

  • vsig – The standard deviation of the velocity distribution of emitted particles.

  • workFunc – The work function. The minimum energy required to emit an electron (eV).

  • fldEvalOff – Field evaluation offset. Presumably the offset from the surface where the field resulting from the particle is evaluated. No use of this in the regression tests.

  • temp – Temperature of the emitting surface (K).

  • fldEnhance – Field enhancement. Multiplies the measured electric field by this amount.

  • fluxMult – Flux multiplier. Multiplies the resulting output current by this amount.

  • A – Coefficient A of the Fowler-Nordheim emission model.

  • B – Coefficient B of the Fowler-Nordheim emission model.

  • Cv – Coefficient Cv of the Fowler-Nordheim emission model.

  • Cy – Coefficient Cy of the Fowler-Nordheim emission model.

  • emOff – The distance away from the object that emission begins, a computational contrivance.

  • maskFunction – The masking function to tailor emission as desired.

  • object – The shape geometry to emit off of.

  • location – The plane from which to emit.

addChildLangmuirEmitter(sourceName, owningSpecies, start, stop, vbar, vsig, emOff, maskFunction, object)

Adds a particle emitter source to a particle species with Child Langmuir properties. Child Langmuir specifies the mean and standard deviation of a velocity distribution.

addRichardsonDushmanEmitter(sourceName, owningSpecies, start, stop, fldEnhance, fldEvalOff, fluxMult, temp, workFunc, emOff, maskFunction, object)

Adds a particle emitter source to a particle species with Reichardson Dushman properties.

addFowlerNordheimEmitter(sourceName, owningSpecies, start, stop, A, B, Cv, Cy, fldEnhance, workFunc, emOff, maskFunction, object)

Adds a particle emitter source to a particle species with Fowler Nordheim properties.
