I also doubt about this. If the Reynold Stress term meets the Boussinesq approximation, where is the "- 2/3 rho k delta_ij"? Do you figure out this problem?

how to calculate implicit stress tensor

hi

is there any way to calculating implicit stress tensor?
we actually working with div of stress tensor, but what for stress tensor itself?

somthing like
fvTensorMatrix blabla
{
fvm::desired()
}
