I am using LAMMPS (14 Feb 2014) and have some questions about fix msst :
For each Us I specify, I obtain one point on the Hugoniot. To get a Hugoniot curve, I would need a series of shocks with different Us.I have read Reed’s paper(about msst):
Reed, Fried, and Joannopoulos, Phys. Rev. Lett., 90, 235503 (2003).
In Reed’s paper,he can carry out the simulation of multiwave structure behavior due to elastic-plastic response or phase transition.
However,‘fix msst’ only get one Up on the Hugoniot for each Us I specify .When plastic wave speed approximates elastic wave speed,I just can not judge whether the ‘Up’ I get is in plastic wave or elastic wave? It seems difficult to get the multiwave structure behavior.Can I get multiwave structure behavior?
Thank you very much for your answer
