you can modify the viscosity or add a momentum resistence to the momentum equation. I prefer the second option. you can find details in following papers.


Swaminathan, C.R., and Voller, V.R., 1993, “On the enthalpy method.” Int. J. Num. Meth. Heat Fluid Flow, Vol. 3, pp. 233-244. Swaminathan, C.R., and Voller, V.R., 1992, “A general enthalpy method for modeling solidification process.” Metallurgical Transactions B, Vol. 23B, pp. 651-664.
