  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.
    - Importing the Mesh
      You import a CAD model consisting of two parts: a large block for the background region, and a smaller part from which the boat was subtracted to represent the overset region.
    - Creating Regions and Setting Boundary Types
      Create regions from the Background and Overset parts.
    - Selecting Physics Models
      A physics continuum must be present, and assigned to both regions, before the Overset region can be coupled to the Background region. You create the physics continuum and activate the several physical models that are required to simulate the forces acting on the hull.
    - Coupling the Regions
      You must create an interface between the background and the overset regions.
    - Generating the Mesh
      Proceed with the mesh creation for the case.
    - Transforming the Overset Region
      Translate the lifeboat nearer to the water surface to decrease the simulation time and give it an initial tilt with a horizontal angle of 35.
    - Creating Eulerian Phases
      The materials corresponding to each of the mixture phases are defined as Eulerian phases.
    - Setting the DFBI Motion and 6-DOF Body
      The 6-DOF motion solver is activated when creating the relevant DFBI motion object and assigning it to the fluid region. For this tutorial, you require the DFBI rotation and translation motion.
    - Defining the VOF Waves
      The VOF Wave model generates a number of field functions that are based on the wave parameters that you define. These field functions can be used as boundary and initial conditions in appropriate nodes on the object tree.
    - Setting Initial Conditions
      The initial conditions are set using field functions that are associated with the previously defined VOF Wave. Initial conditions that are set are the free-surface wave profile, the velocity profile within the phases and the hydrostatic pressure.
    - Setting the Boundary Conditions
      The boundary types have been correctly set previously, so it only remains to set the conditions corresponding to each type.
    - Setting Up Solver Parameters and Stopping Criteria
      As this simulation is transient, it is necessary to set the time step, the maximum number of inner iterations that are permitted in each time step, and the overall physical time for which a solution is obtained.
    - Setting Scenes to Visualize the Solution
      Create scenes to visualize the results as the simulation progresses.
    - Initializing and Running the Simulation
      To verify that the initial conditions applied to the regions are correct, Simcenter STAR-CCM+ allows you to perform just solver initialization to start with and then view the results using an appropriate scene.
    - Summary
      This tutorial introduced the following Simcenter STAR-CCM+ features:
  - 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.
  - 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.
