Hi Monika,
 Only easy solution to apply user-defined forces in NAMD is to use
TCL-FORCES tutorial. Type in google: "force tutorial in namd " and you can
download the pdf in the first link and learn how to be very sophisticated in
applying can also fnd the same tutorial in TUTORIAL
section on NAMD official website. I hope it helps.
