The objectives of the paper are, first, to advance SOCRAT/HEFEST code in the area of molten pool simulation, and, second, to perform the cross-verification of the code. The set of verification data includes the known experiments and CFD calculations. Fluent 6.3 is used as supporting CFD code. The results of the verification are presented concerning the behavior of homogeneous/stratified molten pool and the melting propagation as well. These results shows the applicability of simplified models of SOCRAT/HEFEST to simulation of heat transfer in the stratified molten pool. The possibilities of CFD simulation with k-ε model have been demonstrated for a large range of the inner Rayleigh number up to 1017 .
