Dear All, does OpenFoam inc
does OpenFoam include an Euler-Lagrange-Mapping? I want to map (and maybe smooth too) Lagrangian particle data on an Eulerian Phase.
Did anybody do this already or are there any suggestion where to start with this problem?
any help would be appreciated!
Hi Stephen. I create an alpha-
Hi Stephen. I create an alpha-field from lagrangian data using the code below. Hope it is of some help!
dimensionedScalar("zero", dimensionSet(0, 0, 0, 0, 0), 0.0),
//reset alpha and Ua at each fluid timestep
alpha = dimensionedScalar("zero", alpha.dimensions(), 0.0);
discretePhase::iterator elmnt = particles.begin();
elmnt != particles.end();
label celli = elmnt().cell();
scalar d = elmnt().d();
Np[celli] = Np[celli] + 1;
scalar dVol = M_PI*::pow(d, 3.0)/6.0;
alpha[celli] += dVol/mesh.V()[celli];
Thanks Rasmus, i have alrea
i have already something similar but what i actually need is a real mapping algorithm, which takes care of the fact, that parts of a particle are in different cells. the fields obtained in this way should be smoother. this would be nice for time derivatives of the above mentioned field Np.
thanks for the help!
does anybody else has an idea how to get such smooth lagrangian fields?!
any help would be appreciated
