Hello,

this is more a question of how to understand this term:

fvm::Sp(epsilon/k, k)

This term is on the rhs of the kEqn of the kEpsilon model.

Why is this form used?

Mathematically, one could also write:

fvm::Sp(epsilon)

Hi

the reason is stability of the linear equation system

this would go into the source vector
fvm::Sp(epsilon)

and this in the matrix of the linear equation system.
fvm::Sp(epsilon/k, k)

Regards,
Christian

Hi Christian,

If this fvm::Sp(epsilon) go into the source vector, why dont we use epsilon instead?
