LS-DYNA
=======

Once you are logged in, you can load the LS-DYNA module:

.. code-block:: bash

   module load lsdyna/8.1


After the software is loaded, and you have transferred your input files, you can submit jobs using the slsdyna command:

.. code-block:: bash

   slsdyna -N 1 -n 8 -t 12:00 -i boundary_pre_motion_blowmold.k


You can ask for multiple compute nodes, memory, and CPUs.  The options can be listed using the --help flag:

LS-DYNA scales very well on the cluster.
