    - Prerequisites
      The instructions in this tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Loading the Initial Simulation
      You are provided with a starting simulation that includes the required geometry, regions, interfaces, and reports. Load the initial simulation into a double precision version of Simcenter STAR-CCM+ .
    - Defining the Hyperelastic Material Continuum
      You model the rubber diaphragm with the Neo-Hookean model for hyperelastic materials. This model requires the bulk modulus and the $c_{10}$ coefficient as inputs.
    - Generating the Mesh
      The starting simulation contains predefined mesh operations. These operations generate appropriate meshes for the fluid and solid region.
    - Setting the FSI Coupling
      You define two-way coupled FSI between the solid diaphragm and the fluid overset region.
    - Applying the Constraints to the Solid Region
      To constrain the solid region, you apply four constraints.
    - Setting the Stopping Criteria
      The solid model is highly nonlinear because of the nonlinear geometry, the hyperelastic model, and the contact. To improve the stability and convergence rate of the two-way coupled fluid-structure model, you apply the Dynamic stabilization method.
    - Visualizing the Solution
      A scene has already been created to visualize the fluid velocity and the Von Mises Stress in the diaphragm. To visualize the Von Mises stress and the Plunger motion the relevant displayer properties must be defined.
