| Research Abstract |
Recently we have developed a stabilized characteristics finite element scheme for the Navier-Stokes equations. It is a combined scheme with the characteristics method and a pressure-stabilization method. The matrix of the derived system of linear equations is symmetric and a cheap P1/P1 element is employed. The scheme is, therefore, efficient especially three-dimensional problems.
Stability and convergence of the scheme have been proved. The error estimates are optimal. Consequently, the scheme has mathematical reliability in addition to the computational advantages.
Some other numerical and theoretical results related to the characteristics method have been obtained in this research period.
