Hii all
I have prepared the topology file for urea molecule in AMBER99sb-ildn 
force

field taking the parameters from ffbonded.itp and  ffnonbonded.itp
available in AMBER folder. After simulation the urea molecule is somewhat
distorted. The N-H bond is tilted. Please suggest me how to solve this
problem.


What does "tilted" mean and why do you think it's a problem? The 
molecule won't remain exactly planar all the time.
