A finite element model has been developed for the computation of melting/solidifying process under the action of both buoyancy and surface tension forces. Validated on the square cavity benchmark of Gobin and Le Quéré, it is further extende d to the free surface case where surface tension can drive the flow (capillary flow). A comparison of the results obtained for three boundary conditions applied at the top of the melting pool is performed. It shows that the flow is dominated by buoyancy effect when the pool is deep enough as in the square cavity case of the benchmark.
