Dear  cheri mcferrin,
 
Look into the NAMD manual,  its clearly mentioned here is the link http://www.vegazz.net/ in that look into tutuorial probably this may help you. all the best,

hi all,

i am interested in running a NAMD simulation using o-ter-phenyl (2 phenyl rings attached to a benzene at its ortho positions) as this molecule goes through a glass-transition temperature when the temperature is gradually lowered.  i would like to represent o-ter-phenyl as 3 points in space with a rigid bond distance between these points, each point has zero charge, and the angle between the 3 points is approx 72 degrees.  does anyone know how to run a NAMD simulation when the bond distances and angles are constrained to constant values?

thanks in advance.  cheri mcferrin

That is, I am able to generate the quadrupole tensor which has nonzero components Qxx, Qyy, and Qzz. The latter of which is the calculated quadrupole moment for N2. This is with the bias that the quadrupole is of -++- conformation. I also ran the pop=chelpg option and received the following output which only constrains the dipole moment giving zero partial charges: Breneman (CHELPG) radii used.
