Stability of Thermocapillary Convection in Float-Zone Crystal Growthf buoyancy-driven convection in a cylinder heated from below has served as a test case for the three-dimensional problem. Here, initial results will be reported for thermocapillary convection under zero gravity. A description of the numerical method used to compute the stability bounds will also be given.

Numerical solution of coupled Navier-Stokes and Stefan equationsorresponding linear problem is obtained by means of finite element technique. Estimates for the rate of convergence of the approximate solution to the exact one are given. This method and the estimates are generalized to the case of quasistationary equations. Methods to solve nonstationary problems for Navier-Stokes and Stefan problem are given.

Penalties and Mixed Finite Element Analysis for Variational Inequalitiesarising parameters have to be adjusted in a proper way. In the present paper we discuss as well discretization by finite elements as parameter selection rules. Furthermore the iteration process for solving the discrete problems is investigated.
