Find Kernel Average Misorientations¶

Group (Subgroup)¶

Statistics (Crystallographic)

Description¶

This Filter determines the Kernel Average Misorientation (KAM) for each Cell. The user can select the size of the kernel to be used in the calculation. The kernel size entered by the user is the radius of the kernel (i.e., entering values of 1, 2, 3 will result in a kernel that is 3, 5, and 7 Cells in size in the X, Y and Z directions, respectively). The algorithm for determination of KAM is as follows:

Calculate the misorientation angle between each Cell in a kernel and the central Cell of the kernel
Average all of the misorientations for the kernel and store at the central Cell

Note: All Cells in the kernel are weighted equally during the averaging, though they are not equidistant from the central Cell.

Parameters¶
