const [virtual]

the dragfunction K used in the momentum eq.

ddt(alpha*rhoa*Ua) + ... = ... alpha*beta*K*(Ua-Ub) ddt(beta*rhob*Ub) + ... = ... alpha*beta*K*(Ub-Ua) NB ! ***************************** for numerical reasons alpha and beta has been extracted from the dragFunction K, so you MUST divide K by alpha*beta when implementing the drag function NB ! *****************************

Implements dragModel.
