GENCORE Version 1.1

Authors: William M. Chan

Description:

This program is used to generate a volume grid with H-topology inside the core of a tube (given by a surface: streamwise in J, periodic in K). The tube may or may not be straight.

   Two options are available for creating the core grid:

   ICORE = 1 : The core grid boundary is taken directly from the surface of
               the tube (rounded core). Break points NJO are introduced to
               form the H-topology. The interior is created by transfinite
               interpolation.

   ICORE = 2   A Cartesian grid slice is created at each station of the tube
               in J, centered at the centroid of the station. This slice is
               rotated to form the core grid slice at each J station such
               that it is normal to the centroid curve locally.

Usage:

  gencore [-i IFILE] [-o OFILE] [-njo NJO] [-core ICORE] [-nkcore NKCORE]

  gencore -help  (to get usage)

Argument	Description
IFILE	input filename
OFILE	output filename (default = coregrid.dat)
NJO	NJO = 0 to determine circumferential break points automatically, NJO > 0 to specify circumferential break point location
ICORE	ICORE = 1 to generate rounded core, ICORE = 2 to generate box core
NKCORE	NKCORE = 0 auto-determine number of points in K and L in core, NKCORE > 0 use NKCORE for number of points in K and L in core
