Dear foamers,



I installed the version 1806 of openfoam by following step by step the following link:

https://www.openfoam.com/download/install-source.php


I did that as there is a new post processing tool in this version which is called reactionsSensitivityAnalysis:
(please have a look at https://www.openfoam.com/releases/op...processing.php)


And there is a tutorial case in /OpenFOAM/OpenFOAM-v1806/tutorials/combustion/reactingFoam/laminar/counterFlowFlame2D/ which includes this functionObjetc in the controlDict:



functions
{
sensitivityAnalysis
{
functionObjectLibs ("libutilityFunctionObjects.so");
type psiReactionsSensitivityAnalysis;
outputControl outputTime;
enabled true;
}
}


However when I run the case, I have the following error :





From function static Foam::autoPtr<Foam::functionObject> Foam::functionObject::New(const Foam::word&, const Foam::Time&, const Foam::dictionary&)
105 in file db/functionObjects/functionObject/functionObject.C at line 108.

As I can see in /home/maryam/OpenFOAM/OpenFOAM-v1806/src/functionObjects/field/Make/file, the library name is libfieldFunctionObjects and not libutilityFunctionObjects. I change that and I have :

Anyone has experience with this reaction sensitivity analysis tool ? Is it working ? It is so strange that the tutorial case does not work.



Anyone can help me with that ? Am I doing a mistake or is there a bug ?



Thanks in advance

No one can help me with this post process tool ?

I tried the tutorial case of openFoam, the gri in solver/combustion/chemFoam. If you put :


functions
{
sensitivityAnalysis
{
libs ("libfieldFunctionObjects.so");
type psiReactionsSensitivityAnalysis;
writeControl writeTime;
}
}


in controlDict, it works fine during the run time. But if you remove the postProcessing folder generated during the run time and you try to generate the same folder after the simulation is finished by running chemFoam -postProcess -func psiReactionsSensitivityAnalysis ,
you have :





--> FOAM Warning :

Is it normal ? Isn't it a bug ?

I have also met this bug on the post-processing psiSpecieReactionRates, which is used to calculate reaction rate of each species in each reaction pathway. When testing the reactingFoam tutorial, counterFlowFlame2D, It works well in run-time postprocessing. While I remove the generated postprocessing file, and use the command：reactingFoam -postProcess, it reports:
Create time

Create mesh for time = 0

I am also confused with this problem. Anyone has some suggestions on solving this issue. We can discuss and solve this bug together.
