9.147. Write Los Alamos FFT File

Group (Subgroup)

IO (Output)

Description

This Filter will create the directories along the path to the file if possible.

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
