fix_modify AtC mesh output command

==================================

Syntax

""""""

.. parsed-literal::

   fix_modify <AtC fixID> mesh output <file_prefix>

* AtC fixID = ID of :doc:`fix atc <fix_atc>` instance

* mesh output = name of the AtC sub-command

* file_prefix = prefix of various generated output files

Examples

""""""""

.. code-block:: LAMMPS

   fix_modify AtC mesh output meshData

Description

"""""""""""

Command to output mesh and associated data: nodesets, facesets, and

elementsets. This data is only output once upon initialization since

currently the mesh is static. Creates binary (EnSight, "gold" format)

output of mesh data.

Restrictions
