hey guys,

i am very desperated. it is really important for me:

is somebody here who has experience in plotting residuals (with p, u, k, e - values) with icoUncoupledKinematicParcelFoam!!

it would be fantastic if there is some advice!

[haakon]

I think icoUncoupledKinematicParcelFoam (puh!) only solves for the particle motions, and not flow. Hence, there is no residuals to plot (since no flow equations are solved).

hello Hakon, thanks mae for your reply. Are you sure? i mean, is there anywhere a information source or somethig like this?

[haakon]

Look at the solver source, icoUncoupledKinematicParcelFoam.C:

while (runTime.loop())
    {
        Info<< "Time = " << runTime.timeName() << nl << endl;

        Info<< "Evolving " << kinematicCloud.name() << endl;

        laminarTransport.correct();

        mu = laminarTransport.nu()*rhoInfValue;

        kinematicCloud.evolve();

        runTime.write();

        Info<< "ExecutionTime = " << runTime.elapsedCpuTime() << " s"
            << "  ClockTime = " << runTime.elapsedClockTime() << " s"
            << nl << endl;
    }

It obviously does not solve any flow equations, so yes, I am sure.

thank you haakon,

i appreciate your help. do you know any solver of this list

http://www.openfoam.com/features/standard-solvers.php

which is easy to handle if you want to transfer your simulation from icoUncoupledKinematicParcelFoam to one of those solvers?

which one would you recommend, especially if you want to plot their residuals..??

i would use reactingParcelFoam, but i am not sure if it can plot residuals with the influence of the particles...does somebody have experience with that?

thank you guys in advance

There is a solver in the latest 2.2.x version on Github called DPMFoam, you could give that a try.

However, I don't understand all your interest in the residuals, but it should be possible to do in DPMFoam, hopefully the same way as you normally do it.

[sanjar]

Thanks for this advice. I updated OF from 2.2.0 t 2.2.2 but there is not such a solver. at least not in this version.
thanks at all

[haakon]

Please read my previous post again: There is a solver in the latest 2.2.x version on Github called DPMFoam.

And for the reference, the sources is here: https://github.com/OpenFOAM/OpenFOAM...angian/DPMFoam

There is also a tutorial associated with that solver, called Goldschmidt, you should look into that to get started with the solver.

[sanjar]

yes, i found it too while researching it. at first i did not really got over the system of gitHub. now i got it. thank you.

[sanjar]

still looking for some god advices and help..:/

Whats the use of these two lines?

laminarTransport.correct();

mu = laminarTransport.nu()*rhoInfValue;
