Hi dear Foamers,
Is there anyone to tell me, how I can display/extract the rate of reaction of global chemistry. I examined the following command:
functions
{
RRfunc
{
type writeRegisteredObject;
functionObjectLibs ("libIOFunctionObjects.so");
outputControl outputTime;
outputInterval 1;
objectNames
(
"RR.CH4"
);
}
}
Although, it gave me "RR.CH4", I couldn't plot the file by the paraFoam. Because its class was "volScalarFieldimensionedInternalField".

Regards
Mo.

Hi MohammadReza

There is no necessary to always plot your results through paraview. If you have results then try to open it in Libreoffice.

Ps: There are some examples of rate of reaction computing in this website as well.

Try to search before asking my friend.

Hi Bobi,

Thank you so much for your reply.
I know.... I searched among all threads in the website. But, unfortunately, I could not find any thing related to my question. However, it may be related to my inappropriate searching keywords. Anyway, your comment doesn't work in my case. Because, I want to demonstrate the reaction rates as contours. Therefore, I would be very pleased, if you show me the referred links...

Cheers
Mo.

Hi Mohammad Reza

I remember there was a guy (Shekari..) who did this reaction rate for OpenFOAM related results.He got inspired from the threads in this forum.

I can say, call him or once again search the threads.

I meet a problem in Openfoam 2.3.0, reactingFoam, i need the data of CH4 reaction rate, but i failed to autowrite it like U or Yi.

First i added this code in the CreatField.H,

volScalarField Rrate
(
IOobject
(
"Rrate",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
mesh,
dimensionedScalar("Rrate", dimMass/dimVolume/dimTime, 0.0)
);

Then, i added this code in YEqn,

forAll(Y, i)
{
if (Y[i].name() != "CH4")
Rrate = reaction->R(Yi);
}

After wmake, it shows

YEqn.H:26:14: error: no match for ‘operator=’ (operand types are ‘Foam::volScalarField {aka Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>}’ and ‘Foam::tmp<Foam::fvMatrix<double> >’)
Rrate = reaction->R(Yi);

Can you tell me how to do that? Thank you very much.
