Description
|
|
"""""""""""
|
|
|
|
The fix performs explicit time integration for particles which interact according with the Total-Lagrangian SPH pair style.
|
|
|
|
See `this PDF guide <USER/smd/SMD_LAMMPS_userguide.pdf>`_ to using Smooth Mach Dynamics in LAMMPS.
|
|
|
|
The *limit_velocity* keyword will control the velocity, scaling the norm of
|
|
the velocity vector to max_vel in case it exceeds this velocity limit.
|
|
|
|
Restart, fix_modify, output, run start/stop, minimize info
|
|
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
|
|
|
|
Currently, no part of USER-SMD supports restarting nor minimization. This fix has no outputs.

|
Restrictions
|
|
""""""""""""
|
|
|
|
|
|
This fix is part of the USER-SMD package. It is only enabled if
|
|
LAMMPS was built with that package. See the :ref:`Making LAMMPS <start_3>`
|
|
section for more info.
