TSCAN Version 1.0

Authors: William M. Chan

Description:

This is a script (Tscan stands for tomographic scan) for computing the cross sectional area of a triangulated object versus x, y or z. The number of slices in x/y/z is specified by the user. Options are available to first rotate the object by a given angle of attack (alpha) and yaw angle (beta). The cross sectional area versus x/y/z data is written to a file and the maximum is also reported. The script assumes the user has the following modules from Chimera Grid Tools installed in BINDIR (default is user path): triged (1.0b), seamcrt (2.0k), curvar (1.0)

Usage:

  Tscan [-ifile IFILE] [-dir DIR] [-alpha ALPHA] [-beta BETA] [-cr XC YC ZC] [-ns NS] 
        [-afile AFILE] [-bindir BINDIR]

  Tscan -help  (to get usage)

Argument	Description
IFILE	surface triangulation filename in CART3D format (default is grid.i.tri)
DIR	scan direction = 1/2/3 or x/y/z (default = 1)
ALPHA	angle of attack in degrees (default = 0.0)
BETA	yaw angle in degrees (default = 0.0)
XC YC ZC	x, y, z coordinates of center of rotation for pitch and yaw (default = centroid of object)
NS	number of slices in x/y/z (default = 11)
AFILE	output filename for cross-sectional area versus x/y/z (default = ax.dat)
BINDIR	location of executables for triged, seamcrt, curvar from CGT (default = user path)
