ABSTRACT
All trivial problems that are solved by using the finite element method require use of the computer. The amount of information to be digested and processed is so great for most problems that it is not possible to perform the calculations manually. Hence, a knowledge of and exposure to the development and use of computer programs or codes become necessary. This chapter presents details of a code for the three one-dimensional problems. A computer code should be concise, but at the same time, it should be properly documented so that the user can understand and employ it without spending an undue amount of time. The explanation of the code can be divided into a number of stages, which include input, computer implementation, and output. The data for intermediate nodes are generated by the computer. Nodal coordinates are supplied along with the node quantities at the node points.
