Validation

Test case 1: Cogeneration

This test-case originates from [ProtoOTGUI2014] and can be found in python/test/t_Cogeneration_std.py.

The purpose of this example is to check:

  • The Central tendency analysis using the Taylor Expansions;

  • the default values calculated for the parameters of a parametric analysis.

The obtained results must be equal to the analytical values.

The points are generated according to the structure of a box design of experiments. This deterministic design of experiments has 8 points obtained by regularly discretizing the pavement [10035.5, 10364.5] \times [2975.33, 3024.67] \times [3901.31, 4098.69].

The minimum value of Ep is 0.0292232 with X=[10364.5 2975.33 3901.31]. The maximum value of Ep is 0.0892884 with X=[10035.5 3024.67 4098.69].
