Summary of MGENREC
NAME
mgenrec - SUTRA utility program to generate a simple mesh
ABSTRACT
MGENREC is an auxiliary program to generate several major data sets
for SUTRA. It can be used to generate the nodewise records (data
set 14B), elementwise records (data set 15B), and element-incidence
records (data set 22). MGENREC assumes: (1) a two-dimensional
rectangular mesh composed of equal-sized rectangles, and (2)
constant parameter values throughout the mesh region. The generated
data sets can be modified manually to obtain irregular elements,
irregular regions, or non-constant parameters.
DATA REQUIREMENTS
MGENREC requires four values to be input:
NX = Number of nodes along X-coordinate
NY = Number of nodes along Y-coordinate
XL = Total mesh length along X
YL = Total mesh length along Y
These values are read, free-format, from the standard input unit
(normally the keyboard). By free-format it is meant that values may
be input in any columns as long as they are input in order (i.e. NX,
NY, XL, YL); they are valid (integer values for NY and NX, floating
point values for XL and YL); and a blank(s), a comma, or a carriage
return separates each value.
OUTPUT OPTIONS
MGENREC creates the file MESHOUT.DAT in the user's current
directory.
