Spectral element method for mixed inhomogeneous boundary value problems of fourth order
The authors investigate spectral methods for fourth order problems subject to mixed inhomogeneous boundary conditions. Results on composite Legendre quasi-orthogonal approximation are established. Numerical experiments demonstrate a high accuracy of the method and the fact that it can be applied even in case where the solution changes rapidly, of exhibits different behavior on subdomains.
