Hello, I am still new to OF.
I have a question about the "rhoEqa.H" file
The solver is "rhoReactingFoam" and in the .C file there was a line :

#include "rhoEqn.H"

but I didn't find this file under the reactingFoam solver folders
could anyone tell me where is this file located and being included ,
and how the OF know which rhoEqn.H file to include in the .C code.

Thanks for giving me some instructions about this question

Hi,

$ pwd
$WM_PROJECT_DIR
$ find . -name 'rhoEqn.H'
./applications/solvers/combustion/PDRFoam/rhoEqn.H
./applications/solvers/combustion/fireFoam/rhoEqn.H
./applications/solvers/lagrangian/coalChemistryFoam/rhoEqn.H
./applications/solvers/lagrangian/reactingParcelFilmFoam/rhoEqn.H
./applications/solvers/lagrangian/reactingParcelFoam/rhoEqn.H
./applications/solvers/lagrangian/sprayFoam/rhoEqn.H
./applications/solvers/multiphase/cavitatingFoam/rhoEqn.H
./src/finiteVolume/cfdTools/compressible/rhoEqn.H
./src/finiteVolume/lnInclude/rhoEqn.H
$ find . -name 'rhoEqa.H'
$

Since your question is about rhoReactingFoam, it uses src/finiteVolume/cfdTools/compressible/rhoEqn.H file.

I have a related question. Through which line does the solver know which rhoEqn.H is to be used?

The directories, where the compiler looks for include files (.H) are set in the Make/options file:
https://github.com/OpenFOAM/OpenFOAM...m/Make/options


For rhoReactingFoam:

     -I. \
    -I$(FOAM_SOLVERS)/combustion/reactingFoam \
...
    -I$(LIB_SRC)/finiteVolume/cfdTools \                           

...
    -I$(LIB_SRC)/dynamicFvMesh/lnInclude
