Keywords
=========

The ``keywords`` module can be used to interact with LS-DYNA keywords.

Overview
--------
The `keywords`` module of PyDyna provides Python libraries to build an Ansys LS-DYNA keyword deck.

Usage
-----
Here's an example of how you can generate a `*SECTION_TSHELL`` keyword:

.. code:: pycon

   >>> from ansys.dyna.core.keywords import keywords
   >>> shell = keywords.SectionTShell()
   >>> shell
   *SECTION_TSHELL
   $#   secid    elform      shrf       nip     propt        qr     icomp    tshear
                      1       1.0         2       1.0         0         0         0
