Los Alamos FFT Writer

Group (Subgroup)

IO (Output)

Description

This Filter writes out CellData from an Image Geometry to a file that is appropriate to use as an input into Ricardo Lebensohn's FFT 3D simulation codes[1].

The format of the file is an ASCII text file with the following space delimited information:

Phi1   Phi   Phi2  X  Y   Z  Feature_ID   Phase_ID

The Euler angles are in degrees. X, Y, Z are integer indices into the Image geometry. Feature ID & Phase ID are the integer values for the feature and phase Starting at One (1).

Example Output
