Abstract:
The computation technology in constructing two dimensional viscous fluid dynamics problems by means of spectral element method is described in this paper. The given method allows to find solution of high accuracy on coarse unstructured grids. The universal algorithm for boundary conditions of different types was developed. Testing problems such as lid-driven cavity flow and backward facing step are presented.
Keywords:Spectral elements method, Navier–Stokes equations, unstructured grids, viscous fluid.
