Hello Everyone,


I am trying to implement a new solver based on reactingFoam.
Currently i am on very early stages and try to implement necessery codes step by step.


My first attempt was to create a scalar that will be read from a dictionary i created. Below code is written in a file named "readThickenedFlameProperties.H" and this header is in the same directory as "reactingFoam.C" and "createFields.H".



IOdictionary thickenedFlameProperties
(
IOobject
(
"thickenedFlameProperties",
runTime.constant(),
runTime,
IOobject::MUST_READ,
IOobject::NO_WRITE
)
);

// Define a scalar for thickening factor

scalar TF = readScalar(thickenedFlameProperties.lookup("thicke ningFactor"));

scalar yfSt = readScalar(thickenedFlameProperties.lookup("fuelSt oicRatio"));

I also created the thickened flame properties file in the tutorial case and compilation works up to this point. ("readThickenedFlameProperties.H" is reactingFoam.C right before "createFields.H")


But when i try to create a scalar field inside the "createFields.H" with the scalar i read from my dictionary, i get an decleration error during compilation.


Piece of code in createFields.H is:


volScalarField& yf = composition.Y("CH4");
volScalarField c("c", 1 - yf / yfSt);


and also in reactingFoam.C


int main(int argc, char *argv[])
{

..
..
..
..
#include "readThickenedFlameProperties.H"
#include "createFields.H"
..
..
}


The error i get is:


In file included from /usr/lib/openfoam/openfoam2112/src/OpenFOAM/lnInclude/postProcess.H:147:0,
from myReactingFoam.C:57:
./createFields.H: In function ‘int main(int, char**)’:
./createFields.H:104:32: error: ‘yfSt’ was not declared in this scope
volScalarField c("c", 1 - yf / yfSt);
^~~~


I know yfSt is defined prior to volScalarField c but it seems there is a problem in communication which is weird.


Do you have any suggestions as to how to overcome this problem ?
I know i could place readThickenedFlameProperties.H inside createFields.H but i want to code them seperately for later usage and extended code.

Best regards.

Without seeing the whole Code of "readThickenedFlameProperties.H", its hard to guess where your error is.


According to the errror message I would guess that you defined your variables in "readThickenedFlameProperties.H" under a different scope. Because of the different scope the program is not able to find your variables defined earlier. Maybe you have to get your variable via the scope resolution operator (:. Take a look on your code and look if you have declared for example a block scope in your "readThickenedFlameProperties.H" file or something else.

Hello,


I overcame this problem by moving my new solver folder to user solver folder inside applications. Though I did not understand why it worked.
