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 <PDF/MACHDYN_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 the :doc:`Howto output <Howto_output>` page for an overview of
|
|
LAMMPS output options.
|
|
|
|
The per-particle values are dimensionless an in the range of zero to one.
|
|
|
|

""""""""""""
|
|
|
|
This compute is part of the MACHDYN package. It is only enabled if
|
|
LAMMPS was built with that package. See the "Build
