Thanks for your answer.
From Reed’s paper,multiwave structure behavior can be simulated.However,I wonder whether ‘fix msst’ in lammps can do that the same as Reed’s program?
Manual tells me that this command performs the Multi-Scale Shock Technique (MSST).Is it the same as Reed’s Msst or a little different from Reed’s?
Programmer who creates ‘fix msst’ in lammps may answer the question.

Thank you very much.
