Dear Sir or Madam,

When I was using COMPASS to conduct energy calculation in Discover Module for ZnO, the job failed with a reminder :can't find parameters for bond.....".

But when I was using the same forcefield COMPASS to do energy calculation using Forcite module for the same material ZnO, the job can continue although the bonds are ingored if there is no parameters for the bonds.

In fact, what I am interested in the non-bond energy, such as dispersion energy and repulsive energy. However, if I still want to use Discover module to do energy calculation for ZnO, can we just ignore the bonds if there are no parameters for them in COMPASS in order to continue the job,please?  For example, how to modify the input file? OR what commands are needed to add to the generated input file, please? (Since I want to obtained the individual contribution of dispersion or repulsive energy but not the total of them, so Discover is preferred.)

Thanks a lot in advance!

Best regards,

Wesley
