A three‐dimensional finite element method for the simulation of thermoconvective flows is presented. Vector‐parallel performances of some preconditioned conjugate gradient methods are compared for solving both large linear systems and the Stokes problem. As significant examples, numerical experiments on the steady two‐ and three‐dimensional Rayleigh‐Bénard convection at high Prandtl number are reported.
