The drag function K used in the momentum eq.

ddt(alpha1*rho1*U1) + ... = ... alpha1*alpha2*K*(U1-U2) ddt(alpha2*rho2*U2) + ... = ... alpha1*alpha2*K*(U2-U1) ********************************** NB! ***************************** for numerical reasons alpha1 and alpha2 has been extracted from the dragFunction K, so you MUST divide K by alpha1*alpha2 when implementing the drag function ********************************** NB! *****************************

Implements dragModel.
