Category 2: Mesh Equations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The boundary conditions in this section involve the mesh motion equations in LAGRANGIAN or
ARBITRARY form (cf. *Mesh Motion* card). These conditions can be used to pin the mesh, specify
its slope at some boundary intersection, apply a traction to a surface, etc. Several more boundary
conditions that are applied to the mesh motion equations but include other problem physics are
also available.
