Use the Release from Grid node to release rays from a user-defined grid of points.

See Release for information on the following sections: Release Times, Ray Direction Vector, Initial Ray Frequency, Initial Phase, Initial Intensity, Initial Radii of Curvature, Total Source Power, Initial Polarization, and Initial Value of Auxiliary Dependent Variables.

Enter Initial coordinates based on space dimension (qx,0, qy,0, and qz,0 for 3D components) for the ray positions or click the Range button () to select and define a range of specific coordinates.

Select an option from the Grid type list: All combinations (the default) or Specified combinations. If Specified combinations is selected, the number of initial coordinates entered for each space dimension must be equal, and the total number of rays released is equal to the length of one of the lists of initial coordinates. If All combinations is selected, the total number of rays released is equal to the product of the lengths of each list of initial coordinates.

For example, suppose a 2D component includes a Release from Grid node with the following initial coordinates:

If All combinations is selected, a total of 16 rays will be released, including every possible combination of the initial x- and y-coordinates. If Specified combinations is selected, 4 rays will be released with initial positions (0,2), (1,4), (2,6), and (3,8).
