  The tutorials in this set illustrate various STAR-CCM+ features for simulating problems with moving geometries and meshes, dynamic fluid body interaction, and rigid body motion:
  - Moving Reference Frames: Rotating Fan
    This tutorial outlines the steps that are required to set up and run a rotating radial fan analysis. It uses the Moving Reference Frame model, a steady-state approach that involves two or more frames of reference that can be stationary or moving relative to each other.
  - Rigid Body Motion: Rotating Fan
    This tutorial models the same radial fan problem as the Moving Reference Frames: Rotating Fan tutorial. However, instead of using the steady-state moving reference frame model, this tutorial uses the transient Rigid Body Motion model with actual mesh rotation.
  - DFBI: Lifeboat with Overset Mesh
    This tutorial demonstrates use of the Overset Mesh feature with free surface flow and DFBI to model the motion of a lifeboat falling into water. Simcenter STAR-CCM+ automates the grid overlapping process.
  - DFBI and AMR: Boat In Parameterized Waves
    In Dynamic Fluid-Body Interaction (DFBI) simulations, you can use Adaptive Mesh Refinement (AMR) to dynamically refine the mesh around a moving 6-DOF body based on the computed flow solution.
    - Prerequisites
      The instructions in this tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Loading the Initial Simulation
      In this tutorial, you are provided with a starting simulation file which includes predefined parameters, and regions.
    - Generating the Mesh
      For the main fluid domain, you generate an anisotropic trimmed cell mesh with refinement around the sea level. With the dimensions of the refinement zone are parametrized with respect to the wave amplitude.
    - Selecting the Physics Models
      This simulation models air and water in the same continuum using the Volume of Fluid (VOF) model. As the fluids are in different phases, you activate the Eulerian Multiphase model and account for the effect of gravity on the water, air, and hull using the Gravity model. The flow is turbulent due to wave propagation and fluid interaction with the hull. To refine the mesh iteratively as the solvers run, you include the Adaptive Mesh Refinement and Adaptive Time-Step models.
    - Setting Boundary Conditions
      You set the initial conditions for the Pressure, Velocity, and Volume Fraction as well as the boundary conditions for the regions.
    - Defining the Motion of the Hull as a 6-DOF Body
      The hull is a rigid body that moves at a constant velocity of 8 knots. In addition to the prescribed motion, the hull moves in response to the force exerted by the surrounding fluid.
    - Defining the Motion of the Fluid Domain
      When defining the 6-DOF body, you applied the DFBI motion (both prescribed and induced by waves) to the fluid region near the hull. To make sure that the hull region remains within the background fluid domain in the boat advancing direction, you set the main fluid domain to follow the translational motion of the hull along the X axis.
    - Visualizing the 6-DOF Body Motion, and Applied Force
      To visualize and monitor the motion and orientation of the 6-DOF body, as well as the fluid force acting on the body, you create DFBI reports as well as the corresponding monitors and plots.
    - Recording the Solution
      For further post-processing, you can create a solution history file that records the absolute pressure, pressure, and volume fraction of water at the hull fluid boundary, and on an isosurface that represents the surface of wave propagation.
    - Visualizing Wave Forcing and Wave Propagation
      To visualize wave forcing the propagation of the waves in the domain, and the pressure they apply to the hull, you create two scalar scenes.
    - Specifying Solver Settings
      For wave simulations, you are advised to use a 2nd-order implicit unsteady solver. For the purpose of this tutorial, a time-step of 0.01 s is sufficient. Real world cases typically require a much smaller time-step.
    - Running the Simulation and Visualizing the Results
      To make sure the waves come into contact with the boat hull and the simulation converges, you specify a large physical time, relative to the time-step. You can then initialize and run the simulation.
    - Running the Solution with a Diagonal Wave.
      To create a diagonal wave, you alter the AdvancingDirection parameter, which controls the direction of the wave.
    - Animating the Boat Movement
      To visualize the movement of the boat during the simulation, you can create an animation of the IsoSurfaceWaves scalar scene.
  - Marine Resistance Prediction: KCS Hull with a Rudder
    This tutorial demonstrates the workflow for setting up a resistance prediction simulation for a marine application.
  - Moving Reference Frames: Marine Propeller in Open Water
    This tutorial demonstrates the workflow for setting up an open water simulation for a marine propeller.
  - Body Force Propeller Method: Marine Self-Propulsion
    One of the challenges in marine engineering is to predict the speed with which a ship hull moves through water in response to the thrust supplied by a spinning propeller. Simcenter STAR-CCM+ provides a methodology by which you can predict this speed.
  - Blade Element Method: Helicopter Rotor-Fuselage Interaction
    The rotating main rotor blades of a helicopter generate a complex flow field that leads to periodic aerodynamic loads on the airframe. Because of these aerodynamic loads, the passenger cabin can be subject to noise and vibration. These aerodynamic interactions affect the performance of helicopters and they can cause structural damage. Simcenter STAR-CCM+ provides a method for simulating the flow generated by rotor blades that does not require you to mesh the blades individually. This method allows you to predict the complex flow field around a helicopter taking into account the fuselage and rotor flow field interaction.
  - Morphing: Cylinder with Boundary Motion
    Simcenter STAR-CCM+ contains a Morphing Motion Model that enables you to define motion on boundary surfaces using several methods.
  - Overset Mesh Small Gap Modeling: Lobe Blower
    Rotary lobe blowers are valveless positive-displacement units. Fluid is pumped by two counter-rotating lobes that are mounted on parallel shafts. Fluid enters through the expanding volume at the suction side of the pump. As the lobes continue to rotate, the fluid is compressed between the lobes and the pump casing and hence transported towards the discharge.
  - Trajectory Motion: Paint Dipping of a Chassis on a Fixed Skid
    Paint dipping is a process by which a component is coated with paint in a dipping tank. Simcenter STAR-CCM+ allows you to simulate this process and therefore study the effects of different trajectories and component speeds.
  - General Remesh: Gerotor Pump with Small Gap
    A Gerotor pump is a unit with an inner and an outer rotor that have different rotational speeds related to their tooth numbers. The dynamically changing volume between the rotors transports the liquid from inlet to outlet.
