When the Intensity computation is set to Compute intensity and power or Compute intensity and power in graded media in the physics interface Intensity Computation section, the Deposited Ray Power subnode is available from the context menu (right-click the Wall, parent node) or from the Physics toolbar, Attributes menu. The Deposited Ray Power subnode computes the total incident energy flux on a surface based on the power of incident rays.

Select the Compute smoothed accumulated variable check box to enter a Smoothing radius r (SI unit: m) The smoothing radius functions like the corresponding setting for the Accumulator (Boundary) node.
