Description
|
|
"""""""""""
|
|
|
|
Define a computation that calculates the damage status of SPH particles
|
|
according to the damage model which is defined via the SMD SPH pair styles, e.g., the maximum plastic strain failure criterion.
|
|
|
|
See `this PDF guide <USER/smd/SMD_LAMMPS_userguide.pdf>`_ to use Smooth Mach Dynamics in LAMMPS.
|
|
|
|
**Output Info:**
|
|
|
|
This compute calculates a per-particle vector, which can be accessed by
|
|
any command that uses per-particle values from a compute as input. See
|
|
:ref:`How-to discussions, section 6.15 <howto_15>`
|
|
for an overview of LAMMPS output options.
|
|
|
|
The per-particle values are dimensionless an in the range of zero to one.
|
|
|
|
Restrictions
|
|
""""""""""""
|
|
|
|
|
|
This compute 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.
