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).
