    Notes: A ‘family’ of tree data structures for adaptive mesh refinement is described and details concerning the associated logic are provided. The data structures encompass triangular elements and quadrilateral elements in two dimensions and quadrilateral bricks in three dimensions. Furthermore, both linear (bilinear) and quadratic (biquadratic) element types, respectively, are developed. Representative refinement results are given for the bilinear, trilinear and biquadratic types and associated performance studies made for the refinement procedure.

    A regularization-stabilization technique for nonlinear conservation equation computations (1988)
    New York, NY [u.a.] : Wiley-Blackwell
    Numerical Methods for Partial Differential Equations 4 (1988), S. 165-171 
    Details

    Topics: Mathematics
    Notes: A regularization procedure for nonlinear conservation equations is introduced and demonstrated to have a stabilizing effect on the numerical solution of the associated approximate problem. Representative results for a least-squares finite-element method are given, and the numerical performance of the stabilization procedure explored. The effect of the regularization term is similar to a local numerical dissipation dependent on the numerical itegration time step.

    Element-by-element vector and parallel computations (1988)

    Notes: Vector and parallel algorithms for finite-element analysis using the element-by-element (EBE) data structure are developed. The algorithms are based on the EBE approach in conjunction with gradient-type iterative solution. The essential idea is to exploit the independent dense local-element matrix-vector calculations and reconfigure them to take advantage of vector or parallel processing capabilities. The ideas also are well suited to finite-element adaptive refinement computations. Specific algorithmic details related to the implementations are given, together with results of speed-up performance studies conducted on the vector and parallel architectures. The basic vector and parallel versions of the matrix-vector product for the EBE scheme are very straightforward modifications of the EBE algorithm, requiring little coding change.
