The following comments are related to the SS1D computer program (a VERY simple, and somewhat dated finite element computer program for one-dimensional steady state analyses).

All files related to SS1D 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 SS1D, 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 SS1D, type

ls ss1d*

You will then see the following listing

ss1d.f
ss1d_ex.dat

The file ss1d.f is the source code (FORTRAN 77). The file ss1d_ex.dat, is the data file associated with the sample analysis described in the user instructions for SS1D.


OBTAINING FILES

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

get ss1d_ex.dat

The sample analysis file ss1d_ex.dat will be copied to your directory with the same name as listed above.

To get the SS1D source code, type

get ss1d.f

The source file will be copied to your directory with the name ss1d.f. Proceed to next compile and link the source. Once this is successfully achieved, the execution of SS1D is as described below.


EXECUTING THE PROGRAM

Assume that the executable file has been called 'ss1d'. To execute the program on the sample file ss1d_ex.dat, consider the following sequence of commands (executed on my workstation, so ignore the " ~ vnk : " prompt):

~ vnk : ss1d

Enter input data file name : ss1d_ex.dat
Enter output print file name : out.prt

<<<<< end of SS1D analysis >>>>>

~ vnk :

The name of the input file (ss1d_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.
