Hello Foamers,
My question might be quite basic. I dont find any appropriate thread or may be I couldn't figured it out properly about this topic.

In my case (OF211), volScalarFields such as Temperature, Ycoal, Ychar, K, rho have been calculated using function objects based on probes (as shown below).

functions
{
oven_hope
{
type probes;
functionObjectLibs ("libsampling.so");
outputControl timeStep;
outputInterval 50;
region oven;
probeLocations
(
(0.1 1.0 0.05) // at wall
(0.15625 1.0 0.05) // 1/4 distance
(0.2125 1.0 0.05) //1/2 distance
(0.26875 1.0 0.05) // 3/4 distance
(0.325 1.0 0.05) // centre
);

fields
(T Ycoal Ychar phiGas K rho);
}
};

but the surfaceScalarField "phiGas" couldn't be predicted based on probes.

Kindly someone share ideas about it please.
Thank you

What do you actually mean by 'couldn't be predicted based on probes.'? Supposedly wrong result? Error?

[Kummi]

Dear HPE, Thank you for your response.
"phiGas" values at all probes ends up with 0 (no changes)

[HPE]

Two quick things out of my head:
- probes return only cell values without interpolation, so the probes at four probe locations above should return the same value if they are inside the same cell.
- phiGas results might be the boundary values, which might be zero at the wall.

Hello HPE,
Yes, probes return cell values, at 5 probe locations mentioned above with 5 different positions along X, I got graphs as shown in the attachment.
~ And about "phiGas" - I'm confused. This is how, phiGas is declared:
https://github.com/OpenFOAM/OpenFOAM...reactingOneDim

//- Total gas mass flux released [kg/m2/s]
surfaceScalarField phiGas_;


phiGas_ == dimensionedScalar("zero", phiGas_.dimensions(), 0.0);


phiGas_
(
IOobject
(
"phiGas",
time().timeName(),
regionMesh(),
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
regionMesh(),
dimensionedScalar("zero", dimMass/dimTime, 0.0)
),

Kindly share if you have any ideas - as how to predict phiGas.
Thank you HPE for your valuable time ^^
