  • GENERALIZED 3-D PAVING : AN AUTOMATED QUADRILATERAL SURFACE Mesh Generation Algorithm
    International Journal for Numerical Methods in Engineering, 1996
    Co-Authors: R. J. Cass, Ray J. Meyers, Steven E. Benzley, Teddy D. Blacker
    Abstract:

    This paper discusses the extension of the paving Algorithm for all quadrilateral Mesh Generation to arbitrary three-dimensional trimmed surfaces. Methods of calculating angles, projecting elements, and detecting collisions between paving boundaries, for general surfaces are presented. Extensions of the smoothing Algorithms for three dimensions are set forth. Advances in the use of scalar sizing functions are presented. These functions can be used to better approximate internal Mesh density from boundary densities and surface characteristics.

  • Seams and wedges in plastering: A 3-D hexahedral Mesh Generation Algorithm
    Engineering with Computers, 1993
    Co-Authors: Ted D. Blacker, Ray J. Meyers
    Abstract:

    This paper describes Mesh correction techniques necessary for Meshing an arbitrary volume with a completely hexahedral Mesh. Specifically, it describes seams and wedges, mechanisms that overcome major hurdles encountered in the preliminary work on the plastering Algorithm. The plastering Algorithm iteratively projects layers of elements inward from a quadrilateral discretization of the volume's bounding faces. Seams and wedges resolve incompatibilities in the Mesh and in the progressing boundary, thus ensuring the correct formation of a hexahedral Mesh from the plastering Algorithm.

  • An Eeffective Mesh Generation Algorithm Using Singular Shape Functions
    Transaction on Control Automation and Systems Engineering, 2001
    Co-Authors: Hyeong Seon Yoo, Jun-hwan Jang, Soo Bum Pyun
    Abstract:

    In this paper, we propose a simplified pollution adaptive Mesh Generation Algorithm using singular elements. The algo- rithm based on the element pollution error indicator concentrate on boundary nodes. The automatic Mesh Generation method is fo l- lowed by either a node-relocation or a node-insertion method. The boundary node relocation phase is introduced to reduce pollution error estimates without increasing the boundary nodes. The node insertion phase greatly improves the error and the factor with the cost of increasing the node numbers. It is shown that the suggested r-h version Algorithm combined with singular elements converges more quickly than the conventional one.

  • International Conference on Computational Science (1) - A Pollution Adaptive Mesh Generation Algorithm in r-h Version of the Finite Element Method
    Computational Science — ICCS 2001, 2001
    Co-Authors: Soo Bum Pyun, Hyeong Seon Yoo
    Abstract:

    In this paper, we propose a simplified pollution adaptive Mesh Generation Algorithm, which concentrate on the boundary node based on the element pollution error indicator. The automatic Mesh Generation method is followed by either a node-relocation or a node-insertion method. The boundary node relocation phase is introduced to reduce pollution error estimates without increasing the boundary nodes. The node insertion phase greatly improves the error and the factor with the cost of increasing the node numbers. It is shown that the suggested r-h version Algorithm converges more quickly than the conventional one.
