# Macro "**sensitivityFASTFunctionFlowrate.{{extension}}**"

## Objective

The objective of this macro is to perform a Fast sensitivity analysis on a set of eight parameters 
used in the `flowrateModel` model described in [](#launcher_introduction_simple_case_problem).

## Macro {{uranie}}

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityFASTFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + macro[language] + "\n"
    + "```"
}}
            
The function `flowrateModel` is loaded from the macro `UserFunctions.C` (the file can be found in 
`${URANIESYS}/share/uranie/macros`)

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityFASTFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc1[language] + "\n"
    + "```"
}}
            
Each parameter is related to the {{tds}} as a `TAttribute` and obeys an uniform law on specific interval:

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityFASTFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc2[language] + "\n"
    + "```"
}}
            
To instantiate the `TFast` object, one uses the {{tds}}, the name of the function and the number of 
samplings needed to perform sensitivity analysis (here nS=500):

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityFASTFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc3[language] + "\n"
    + "```"
}}
            
Computation of sensitivity indexes: 

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityFASTFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc4[language] + "\n"
    + "```"
}}
            
## Graph

{{
    "```{" "figure" "} " + parent_dir +
        "/roottest/build/uranie/doc/sensitivity/use_cases/" + language 
        + "/fast/sensitivityFASTFunctionFlowrate.png\n"
    + ":align: center\n"
    + ":name: use_cases_sensitivityFASTFunctionFlowrate\n"
    + figure_scale + "\n"
    + "\n"
    + "Graph of the macro **\"sensitivityFASTFunctionFlowrate." + extension + "\"**" + "\n"
    + "```"
}}
            
## Console

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/build/uranie/doc/sensitivity/use_cases/" + language 
        + "/sensitivityFASTFunctionFlowrate_clean.log"
    + "\n"
    + ":language: none\n"
    + ":lines: " + console[language] + "\n"
    + "```"
}}
