| Abstract: | 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. |
