Vectorized solver, by FFTs, for a block tridiagonal system that arises from finite difference approximations on a staggered grid to three-dimensional separable elliptic partial differential equations with variable coefficients in one direction and constant coefficients in two directions. Classes : I2b4b . Solution of discretized elliptic equations Type : Fortran subroutine in CRAYFISHPAK library. Access : Proprietary. Many implementations available. Precision: Double. Note : Vectorized Usage : CALL S3CFSS (LDIMF, MDIMF, F, 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.
