Comments
- This keyword maps to /SET.
- The adding and removing of springs in *SET_DISCRETE_GENERAL depends on the order of the TYPE options used.
- The option “_TITLE” can be added to the end of this keyword. When “_TITLE” is included, an extra 80 characters long line is added after the keyword input line which allows an entity title to be defined.
