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 minimum and the maximum values are computed automatically thanks to
the distribution of the variables. The minimum value is the quantile at the
probability of 0.05 and the maximum one is the quantile at the probability of
0.95. The number of used values per variable is by default 2.

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 :math:`[10035.5, 10364.5] \times [2975.33, 3024.67] \times [3901.31, 4098.69]`.

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

  .. image:: /developer_manual/validation/fieldModel_diagramWindow.png
      :align: center

- click on 'Model definition' button of the diagram: an item 'Definition' appears
    - add an input: the 'Probabilistic model definition' button of the diagram is enabled
    - add an output: the 'Model evaluation' button of the diagram is enabled

- click on the 'Model evaluation' button of the diagram
    - a wizard appears, click on Cancel

- click on the 'Probabilistic model definition' button of the diagram
    - a window appears, select X0
    - the  'Central tendency' button of the diagram is enabled

- click on the 'Central tendency' button of the diagram
    - a wizard appears, click on Cancel


FMI model
'''''''''

- create a new study and add to it a FMI model

- load the FMU file at python/test/fmu/linux64/deviation.fmu

- there must be 4 input variables, 1 output

- change the value of F=33e3 and click on 'check model' button then y=14.32

  .. image:: /developer_manual/validation/fmuModel.png
      :align: center

- in the "Properties" tab the model type should be "Co-Simulation"

- same on windows, load the FMU file at python/test/fmu/win64/deviation.fmu

- select F as input, y as output, change the F value and evaluate

YACS model
''''''''''

- create a new study and add to it a YACS model

- edit the model python code with:

  .. code-block:: python

      def _exec(X0, X1):
          Y0 = X0 + X1
          return Y0

- change X0 and X1 values and check Y0 value

- create a probalistic model and a probablitic design of experiments:

  - default size: 100

- evaluate the DoE, click run and quickly stop the analysis

  - a message says that the job has been detached.

  - save the study, close persalys

  - re-open persalys and relaunch the analysis

  - the DoE gets evaluated almost instantly
