The following comments are related to the T1DHC computer program (a VERY simple, and somewhat dated finite element computer program for one-dimensional transient heat conduction analyses).

All files related to T1DHC are found in a public "ftp" site on our server. To access this directory from your machine, make sure youčre in the directory into which you want to transfer T1DHC, and then type (followed by a carriage return - this holds for all subsequent commands)

ftp ce.udel.edu

This connects you to our department server. At the prompt for user name, type:

anonymous

For password, simply type your e-mail address. This places you in the directory home ftp directory. Then change directories by typing

cd pub/kaliakin

This puts you in my personal ftp directory. To see all the files associated with T1DHC, type

ls t1dhc*

You will then see the following listing

t1dhc.f
t1dhc_ex.dat

The file t1dhc.f is the source code (FORTRAN 77). The file t1dhc_ex.dat, is the data file associated with the sample analysis described in the user instructions for T1DHC.


OBTAINING FILES

Let's turn our attention next to getting the sample analysis files. To get these files, type

get t1dhc_ex.dat

The sample analysis file t1dhc_ex.dat will be copied to your directory with the same name as listed above.

To get the T1DHC source code, type

get t1dhc.f

The source file will be copied to your directory with the name t1dhc.f. Proceed to next compile and link the source. Once this is successfully achieved, the execution of T1DHC is as described below.


EXECUTING THE PROGRAM

Assume that the executable file has been called 't1dhc'. To execute the program on the sample file t1dhc_ex.dat, consider the following sequence of commands (executed on my workstation, so ignore the " ~ vnk : " prompt):

~ vnk : t1dhc

Enter input data file name : t1dhc_ex.dat
Enter output print file name : out.prt

<<<<< end of T1DHC analysis >>>>>

~ vnk :

The name of the input file (t1dhc_ex.dat) is prompted for above, as is the name of the output file (out.prt). The latter is an ASCII text file that contains the results of the analysis.
