Customized version of FERUM 4.1

To perfrom structural reliability analysis.

Work in progress, many changes are experimental, expect nothing ;)

Changes

• additional distribution functions:

  • Generalized extreme value distribution (GEV)
  • 3-parameter lognormal distribution
  • sample based distribution - fitting kernel to the sample
  • non-parametric distribution - vector based definition
  • powered distribution type option, F_n(x) = F_1(x)^n

• new methods:

  • lambda method, inspired by doi.org/10.1016/j.strusafe.2015.09.004
  • directional sampling with adaptive response surface (ADIS), inspired by doi:10.1016/j.probengmech.2010.11.002

• solvers:

  • COBYLA for FORM (relying on NLopt)

• general:

  • small changes in the code: too many to list and were not properly recorded...
