addforce for ReaxFF simulation

Hi Ray,

For EAM, the units are metal, while ReaxFF, real.

The ‘1.0’ I use is already very large to EAM. I use even 0.0001 can effective drive the frozen region.
However, for ReaxFF, even I use ‘10^6’ for the force, the frozen region never move at all.

It is surprising to me.




Fix aveforce works for me with reax/c. I added the command to one of the reaxc examples and it worked as it should. Please try again with updated version and use the example inputs.
