The getDescription() method of the ComputedNumericalMathEvaluation class only returns the description of the input variables

[regis.lebrun@…]

Depending on the wrapper description (i.e. the XML file), one gets a NumericalMathFunction which description can contain either the description of the input and output variables (such as poutre.xml) or the description of the input variables only (such as wrapper.xml). It is mandatory for a NumericalMathFunction to provide the description of both the input and the output variables in order for the composition mechanism to work.

I fixed the bug in my branch, by checking if the description found in the XML file corresponds to the full description of the variables, to the description of the input variables only in which case a generic name is given to the output variables, or if there is a real mess in the XML file.
