Hi,

from my understanding if i want to create an object from a class i do the following:
classname objectname;
afterwards i can access the member functions of this class:
objectname.read();

when running a solver the main-function is executed.
however, within the main-function i don't see where the object of the pimple solver is created. i just see for example (reactingMultiphaseEulerFoam.C):

// --- Pressure-velocity PIMPLE corrector loop
while (pimple.loop())
{
fluid.solve();
fluid.correct();

#include "YEqns.H"

if (faceMomentum)
{
#include "pUf/UEqns.H"
#include "EEqns.H"
#include "pUf/pEqn.H"
}
else
{
#include "pU/UEqns.H"
#include "EEqns.H"
#include "pU/pEqn.H"
}

fluid.correctKinematics();

if (pimple.turbCorr())
{
fluid.correctTurbulence();
}
}

can anybody please explain how the object fluid or pimple is created? are those created in the header files and imported with #include? if yes, where is the code part that generates those objects automatically and gives these objects its names.
also,i don't understand how functions are executed only by including some header files.
do these header files contains certain code that are executed automatically?

thanks in advance.

hi geth,

Have you figured out this problem? I have the same confusion.

Hi,

There is nothing to be confused about. Back then i didn't know anything about code structure.

If you want to find how the code is written, you need to dig deeper and look how its done.

If you are new to openfoaming coding, i suggest you start with icofoam and look how it is coded.

Regards
