Good morning,
I am doing simulations using compressibleInterFoam, how can I write in simulation foalders the mDotAlphal() field associated with condensation and evaporation ? I am using the SchnerrSauer model. Foam::Pair<Foam::tmp<Foam::volScalarField>> Foam::twoPhaseChangeModels::SchnerrSauer::mDotAlphal() const { const volScalarField& p = mixture_.U().db().lookupObject<volScalarField>("p" ); const volScalarField pCoeff(this->pCoeff(p)); const volScalarField limitedAlpha1 ( min(max(mixture_.alpha1(), scalar(0)), scalar(1)) ); return Pair<tmp<volScalarField>> ( Cc_*limitedAlpha1*pCoeff*max(p - pSat(), p0_), Cv_*(1.0 + alphaNuc() - limitedAlpha1)*pCoeff*min(p - pSat(), p0_) ); } |

Hello Nicola,
I don't know if it will work on your specific case, but have a look to the writeObjects function object. It allows to write variables which are registered to the database but not written to disk by default.
Regards, Yann |

Hi Nicola,
A simple way to do it could be creating a variable in createFileds.H and the assign the value of mixture->mDotAlphal(); somewhere after mixture->correct; Beware that mDotAlphal() is a Pair, so you may use two different volScalarField objects to write each component on. You can set the IOobject options to NO_READ and AUTO_WRITE, so the variable will be written in each folder and you won't need to set a value in the 0 folder. Regards, Lorenzo |
