	figures.ps		
	fig1.eps		fig2.epa		fig3.eps		
	fig4.eps		fig5.eps		fig6.eps
	fig7.eps		fig8.eps		fig9.eps		

	The file potlin is the binary file that runs the program potlin.c 
It has four input files: ex1.in, ex2.in, ex3.in, ex4.in and the related
output files ex1.out, ex2.out, ex3.out, ex4.out

	The file nonconvex is the binary file that runs the program nonconvex.c
It has two input files: ex5.in, ex6.in, and the related output files
ex5.out, ex6.out 

	The file potquad is the binary file that runs the program potquad.c 
It has one input file: ex7.in, and the related output file ex7.out

	The file elastlin is the binary file that runs the program elastlin.c 
It has one input file: ex8.in and the related output files ex8.out

	The file elastquad is the binary file that runs the program elastquad.c
It has one input file: ex9.in,  and the related output files ex9.out

	cboxe.h, cbox2.h, cbox3.h, and cbox5.h are the header files for the
above programs.
	
	The source codes for all these programs are provided.

	The file notes.tex, notes.dvi, or notes.ps should be read before
running the above programs. The file notes.tex describes the above
computer programs and the input and output files. This file uses plain 
TeX format which  can be easily translated into another version, like 
LaTex; the corresponding .dvi  or .ps file can be viewed or printed 
depending on the facility available to the reader. The figures 
Fig. 1 through Fig. 9, referred to in the text of the notes.tex file, 
are provided  in the .eps format, which sometimes requires
eps-conversion; in case such a conversion is not possible on certain
computers, these figures are also provided in the file  figures.ps 
which can be viewed or printed. All these fifures are also available in
Appendix B of the above book.

	The instructions for creating the input files, running the programs,
and opening the output files are given in details in the files notes.tex
(or notes.dvi, or notes.ps), and also in Appendix B of the above mentioned
book. 

	The above programs solve a large number of interior or exterior boundary
value problems in convex and nonconvex regions involving potential flows,
heat conduction, porous media flows, simple blood flows, and elastostatic
displacements, stresses and strains. Since these programs are structured in 
different modules, they can easily be modified to solve other types of
boundary 
value problems. Nine benchmark problems, described in the file 
notes.tex or in Appendix B of the above book are solved using these
programs. 
Although they have been carefully tested on PCs, yet they are provided 
without any warranty. There is no warranty that the programs will produce 
mathematically correct results or that they are free from errors. No
warranties 
are made concerning the conditions under which the source codes can be
recompiled.
Neither the publisher nor the author can accept responsibility for any
incompatibilities between the users computer system and the IBM-PC, MS-DOS,
or UNIX operating  systems under which these programs were developed. 
The publisher and the author deny any responsibility for errors,
misstatements, or omissions that may or may not lead to injuries or loss of 
property. 

	If you have suggestions, please write to the publisher or the author.
