Hello all,

I'm a beginner on MS, and I use it with the COMPASS force field in Forcite. My problem is that, in the calculated non-bond energy components, the hydrogen bond energy is always 0 (other proprties look normal). The output .txt file containing energy parameters only specifies the parameters for electrostatic terms and van der waals terms. I wonder whether COMPASS explicitly calculate hydrogen bonds or not. Or did I miss any setting that enables the calculation of hydrogen bond energy? If not, is there a way to extract information about hydrogen bond (e.g., energy, bond length, etc.)?

Thanks.
