Polycrystal ComponentThe component creates a threedimensional grid of cubic instances of the Single_crystal-component,through which the rays are propagated. The component relies on a list of possible orientations and stretches of the initial unit cell and a list correlating each voxel of the polycrystal to an entry in the list of rotations and stretches. Example: Polycrystal( MapFile= "polycrystal_1layer_2orts.map", OrientationsFile= "stretch_2orts.orts", ReflectionsDatafile= "GeReduced.lau", xwidth= 200e-6, yheight= 200e-6, zdepth = 50e-6, DeltadOverd = 0.001, Mosaicity = 1, SigmaAbsorbtion = 0.0, SigmaIncoherent = 0.0, MaxNumberOfReflections = 1, ProbabilityOfTransmission = 0.5, ax = 5.6579, ay = 0.0000, az = 0.0000, bx = 0.0000, by = 5.6579, bz = 0.0000, cx = 0.0000, cy = 0.0000, cz = 5.6579 )
