Dear Sir/Madam

I am trying to calculate vdw and electrostatic energy for bulk urea
molecules using VMD NAMDenergy plugin. I have around 160 urea molecules in
the bulk out of 250.
 The electrostatic and vdw energy for bulk urea molecules are -14257.7559

  -348.793427 kcal/mol, respectively.

The protocol, i have used for this calculation is attached as image file.
and i have used amber generated coordinate file for this calculation.

why i am getting very high value ?
Is there any selection problem in my selection ?
