Philip Eisenlohr d5f9f543ca Script to generate PNG image from given column (or 2D data in overall ASCIItable) with custom colormap and pixel sizes.
Supersedes “imageFromData” from “Code” repository.

Philip Eisenlohr 9eae665365 fixed ‘too many files open’ issue when processing a large list of input tables. 2015-02-11 17:22:47 +00:00
Haiming Zhang eed00007f9 Re-write the script:
1. replace curve_fit with leastsq, which supports the analytical Jacobian
2. specify a "class" (contains both residum and jacobian) for each criterion.
3. add the calculation of Jacobian

Martin Diehl 6140285ddd small changes (use ip.x instead of 1_ip). Probably we should modify postResults to use the 1_, 2_, 3_, standard notation for ip as well 2015-02-07 18:13:51 +00:00

Haiming Zhang f3bab46275 addthe Cazacu–Barlat (CZ) yield criterion (3D and 2D), Banabic–Balan–Comsa (BBC) Yield Criterion. 2015-02-07 16:58:57 +00:00
Haiming Zhang cdb7795956 1. Add default boundary constraint(no constraint) and initial guess to the dictionary
2. With the boundary constraint of exponential term, now non-quadratic yield criteria (isotropic Barlat 1991, anisotropic Barlar 1991, Hosford) take effect.

Test User 239b34e606 Added report of SUCCESSFUL test for Revision 3909 2015-02-07 10:21:48 +00:00
Haiming Zhang 0350b1829c 1. Replace curve_fit(see minpack.py) with curve_fit_bound(see damask/util.py), now the boundary constraint can be applied.
2. Transfer the output information into dictionary 'fittingCriteria', compact subroutine 'fit'.
2015-02-06 14:01:04 +00:00
Haiming Zhang ce09e992cc 1. Change yieldStress from 'list' to 'numpy.arrary', thanks to Martin's suggestion (3907);
2. Change '3*3' Cauchy stress tensor to '1*6', now the number of input 'xdata' for fitting is 6*Points, which is less than the former 9*Points.
