Morse Potential: efficient special case of RepulsiveExponential #20

Open sannant opened 4 years ago

sannant commented 4 years ago

The repulsive exponential is the attractive exponential squared. Hence the exponential needs to be evaluated only once.

(See "Modeling adhesive hysteresis" equation 3)

sannant commented 3 years ago

Not that we experienced that for DMT-like adhesion, the repulsive part of Morse is too soft. I think this potential is only apprpriate for short-ranged, JKR-like adhesion.

sannant commented 3 years ago

Morse is implemented right now but not in the efficient way.
