The Deposited Ray Power node is used to compute a heat source based on the attenuation of rays as they propagate through a domain with a complex refractive index. This feature is available when the ray power is solved for. The Deposited Ray Power node defines a dependent variable with default name <name>.Qsrc, where <name> is the name of the Geometrical Optics physics interface, for example gop.Qsrc.
