Solves the standard five-point finite difference approximation on a staggered grid to the two-dimensional Helmholtz equation in spherical coordinates on the surface of the unit sphere. (Vectorized version of FISHPAK's HSTSSP). Classes : I2b1a1a . Poisson (Laplace) or Helmholtz equation on a rectangular domain (or topologically rectangular in the coordinate system) Type : Fortran subroutine in CRAYFISHPAK library. Access : Proprietary. Many implementations available. Precision: Double. Note : Vectorized Usage : CALL H2CFSS(BDTS,BDTF,BDPS,BDPF,MDIMF,F,PERTRB,SAVE,W) Details : Documentation Sites : (1) ARNO
ARNO: Silicon Graphics Origin 2000, National Institute of Standards and Technology (NIST), Gaithersburg, MD. Available to NIST staff. Precision: Double. Note : Vectorized Those logged in to arno.nist.gov or amur.nist.gov may access this module as follows. Link : Library coded in single precision, but converted to double via the f90 -default64 option.
