A displacement file is a flat text file in versions 5.10 and 5.20, which can be created and edited by any text editor such as Notepad.
In CAESAR II Version 13, a displacement file can be in either fixed format .disp or comma separated value format .csv.
For both formats, use * to indicate a comment line in the displacement file. You can type anything on the line following the *.
Displacement files can have as many comment lines as necessary.
The comment line is not counted in line numbering in the file format descriptions.
