reactionSensitivityAnalysis

Description

The reactionsSensitivityAnalysis function object computes indicators for reaction rates of creation or destruction of species in each reaction.

This function object creates four data files named:

"consumption"    :   consumption rate
"production"     :   destruction rate
"productionInt"  :   integral between dumps of the production rate
"consumptionInt" :   integral between dumps of the consumption rate

input	-	-
output file	dat	$FOAM_CASE/postProcessing/<FO>/<time>/<file>
output field	-	-

Usage

Example of the reactionsSensitivityAnalysis function object by using functions sub-dictionary in system/controlDict file:

reactionsSensitivityAnalysis1
{
    // Mandatory entries (unmodifiable)
    type            reactionsSensitivityAnalysis;
    libs            (fieldFunctionObjects);

    // Optional (inherited) entries
    writePrecision  8;
    writeToFile     true;
    useUserTime     true;
    region          region0;
    enabled         true;
    log             true;
    timeStart       0;
    timeEnd         1000;
    executeControl  timeStep;
    executeInterval 1;
    writeControl    timeStep;
    writeInterval   1;
}

where the entries mean:

Property	Description	Type	Required	Default
type	Type name: reactionsSensitivityAnalysis	word	yes	-
libs	Library name: fieldFunctionObjects	word	yes	-

The inherited entries are elaborated in:

• functionObject
• writeFile

Usage by the postProcess utility is not available.

Notes on entries

• Function object only applicable to single cell cases.
• Needs a chemistryModel chosen.
