  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.
  - 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.
    - Loading the Starting File
      You start this tutorial by loading a simulation file that includes four imported mesh parts and a physics continuum that already defines the flow physics. As this tutorial is focused on the remeshing strategy the steps for choosing physics models are not required.
    - Setting Up Mesh Operations for Gerotor Volume
      When remeshing happens, the mesh pipeline ensures that the pump is positioned in a correct position. Besides, due to the small gaps you apply Directed Mesh to reduce the cell count in the axial direction of the pump.
    - Creating Part Contacts and Generating Volume Mesh
      Before executing the mesh pipeline, you must create weak in-place contacts that connect the inlet, and outlet parts to the gerotor volume. These contacts become interfaces under regions.
    - Setting Time-Step Size to Match Motions
      When simulating motions, the time-step size should be matched to the mesh movement.
    - Setting Up the Remeshing with Cyclic Matching
      The Remeshing model is added within the existing physics continuum. The remeshing process is controlled by both the Remeshing model and the Remeshing solver.
    - Setting Up Morphing Motion and Boundary Conditions
      The motion of the gerotor walls is realized using the morpher.
    - Visualizing Mesh Movement and Pressure Distribution
      You visualize the mesh movement and the fluid velocity on a section plane.
    - Running the Simulation
      To achieve a good mass conservation, the flow should converge well after each mesh movement. Therefore, you set the maximum inner iteration 10 and increase the under-relaxation factor of pressure to 0.3. In total, the simulation runs 720 time steps, which corresponds to two full rotations of the pump.
