gcouegnat/ffth

C++

Requirements

Eigen
FFTW

Define environment variables EIGEN_INC, FFTW_INC and FFTW_LIB (see Makefile)

Example

In folder test/

../ffth --input IM64.raw  --nx 64 --ny 64 --nz 64 --loading load.inp --material mat.inp  --phase phases.inp

Input files

IM64.raw

Unsigned char (uint8) : phases from 0 to n (max. 255)
load.inp
```
E11 E22 E33 E12 E23 E13
```
mat.inp
```
nmat

C^0_ij [6x6]
a^0_i [1x6]

C^1_ij [6x6]

Indices are contracted using a modified Voigt notation 11 --> 1, 22 --> 2, 33 --> 3, 12 --> 4, 23 --> 5, 13 --> 6
phases.inp
```
nphase
matnum theta_x theta_y theta_z

```
where theta_x, theta_y ,theta_z are rotation angles around x, y, z axis. (cf. rotate_matrix in src/utils.h)
