Martin Diehl 302a5017d4 Merge branch 'development' into 12-fixOrientationSampling 2018-03-13 04:12:03 +01:00
Martin Diehl 2ceb3aeea0 not all variables were consistently renamed 2018-03-13 03:56:02 +01:00
Martin Diehl 44e5644e78 fixed random Gaussian sampling
sampling needs to be performed from unfiform misorientation, NOT uniformly distributed rotations
for Fiber, compute uniform tilt of Fiber axis

Martin Diehl e1c4c7e6e8 wrong indices in matrix rotation
fixing this resolves issue 14: "Poor performance after load case rotation"

Martin Diehl 5c908e44ec correct scaling for FWHM
FWHM was wrong by a factor of approx 2.
Analytic expression can be found in https://en.wikipedia.org/wiki/Gaussian_function

Martin Diehl 9173d12d14 correct algorithm for sampling of uniform orientations and fix for Halton series
Halton series gives strange results for large prime numbers, now always starting with 2 for first dimension, 3 for second etc.
Consecutive Halton numbers for rejection sampling seem to cause problems (i.e. introduce patterns).
Algorithm for uniformly distributed orientations with FWHM specified is taken from https://math.stackexchange.com/questions/131336.
WIP: Gauss filtering is currently not implemented!
