What is the specific physical meaning of CFNM extracted from the history output after defining surface-to-surface contact during the drop hummer test in ABAQUS?

When simulating a drop hummer test, it is common to set up surface-to-surface contact between the drop weight and the specimen. Then CFNM, as indicated in the history output, represents the impact force-time curve. Could you explain the physical meaning of CFNM?

thanks!
