Uses Laplace's equation to generate a two-dimensional boundary-fitted grid. Creates a curvilinear coordinate system that maps the unit square onto a region whose boundary is input by the user. The boundary must be divided into four sides: bottom, left, top, right. Classes : E3b . Grid or knot generation K6b . Grid or knot generation P . Computational geometry (search also classes G and Q) Type : Fortran 77 subroutine in ELLIPGRID package. Access : Public domain. Portable. Precision: Single. Usage : CALL LAPGRID (XB, YB, XL, YL, XT, YT, XR, YR, NB, NL, NT, NR, NUMI, NUMJ, X, Y, ALPHA, BETA, GAMMA, CENTER, TOL, OMEGA) Details : Fullsource Sites : (1) ITL
