  <h1>
    A hyperelastic oscillatory Couette system
    <!-- Insights from a minimal elastohydrodynamic problem -->
    <!-- A minimal setting with coupled elastic solid--fluid interactions -->
    <!---Shear flow benchmark for testing elastic solid--fluid coupling algorithms--->
  </h1>

  <hr>
  <p style="font-size: 16px; text-align: justify;">
    The page provides an interactive sandbox for gaining intuition of flow--structure interaction in a minimal setup
    where an oscillatory wall (top, at \( y / L  = 1\)) drives a fluid (above the dashed line) which in turn affects an hyperelastic solid (below the dashed line). This setup, while minimal, is dynamically rich, which you can visualize by accessing a drop-down menu for choosing behavioral archetypes (such as seeing harmonics in the solid). If you want more fine-level control, you can utilize sliders to change dynamical parameters. To access the physical meaning of these parameters, please hover over the underlined text.
