Hello community,



Why fvOptions radialActuationDiskSource has in its Usource line the contribution of each cell volume divided by total volume PLUS the normalized radial distribution already considered in Tr[i]?



Here is the code:

const scalar a = 1.0 - Cp/Ct;     const scalar T = 2.0*rhoRef*diskArea_*mag(Uref)*a*(1.0 - a);       forAll(cells, i)     {         const scalar r2 = magSqr(mesh().cellCentres()[cells[i]] - avgCentre);           Tr[i] =             T            *(radialCoeffs_[0] + radialCoeffs_[1]*r2 + radialCoeffs_[2]*sqr(r2))            /intCoeffs;           Usource[cells[i]] += ((Vcells[cells[i]]/V_)*Tr[i]*E) & Uref;     }
