GaussianEnergyFluxBC

Describes an incoming heat flux beam with a Gaussian profile

This boundary condition is the finite element analog of FVGaussianEnergyFluxBC. It computes an influx of energy from a beam (e.g. laser) with a Gaussian spatial profile. The flux is given by

where is the total power of the beam, is the radius at which the intensity falls to of its axial value, and is the normed distance from the point at which we're evaluating the flux to the centerpoint of the beam. This functional form of the beam flux is taken from Wikipedia. The negative sign on the flux indicates that the flux is incoming. This class assumes that the beam impinges perpendicular to the surface.
