Abstract
A general spectral method is proposed for the numerical solution of th e steady 2D thermal convection equations. The spatial discretization i s performed by means of Chebyshev orthogonal collocation which is prec onditioned by a standard Galerkin finite element technique. Non-trivia l geometries are treated by combining coordinate transformation to dom ain partitioning. Natural convection problems are thus solved in compl ex geometries while keeping the attractive properties of spectral meth ods.
