Currently I am doing FEM using java. The input file should be in ASCII format.

I have an example of the programming where it supplied all related documents. I try to run the file using .txt format file as the input data but nothing happen. In the example, it use an extension file of .fem file as an input data. The data in these two file is similar.

Therefore, I need some help in understanding what happen here and does it possible for me to convert the .txt file to .fem file?

Thank you in advance.
