Tutorials
Tutorials show you how to use Simcenter STAR-CCM+ for various applications in a step-by-step format with recommendations for setup, initialization and steps of the solution process specific to the application. Macro and simulation files are available for download for a large proportion of cases.
- Using Tutorial Macros and Files
  Macros, input files, and final simulation files for a range of tutorials are provided as an optional download package on the Support Center website. These macros and final simulation files are provided as an aid to the written tutorials, so that you can check your final results against the downloaded files, or against a simulation that is built and run using the macros.

- Motion
  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.
    - Mesh Generation
      In order to achieve accurate resistance predictions, you are recommended to use trimmed hexahedral meshes with local refinements and prism layers along the walls of the wetted surface. In order to refine the computational mesh only where it is necessary, you create volumetric controls with particular shapes. A particular cell size is then assigned to these volumetric controls.
    - Physical Setup
      Flow resistance simulation is a complex transient multi-physics problem.
    - Visualization and Data Analysis
      Here, you create several plots and graphs for visualizing the results.
    - Setting Solver Parameters and Stopping Criteria
      A resistance prediction analysis is a transient simulation for which you must specify the time-step, the number of inner iterations per time-step, and the physical time. Additionally, you can set numerical parameters such as under-relaxation factors to enhance convergence per time-step.
    - Running the Simulation
      You are advised to run this tutorial on a multi-core machine with four cores or more. Depending on the specifications of your computer, this tutorial takes one to two days to complete.
    - Visualizing the Results
      You can follow the progress of the solution using each of the scenes that you created previously.
    - Comparing with Experimental Results
      For the Gothenburg Workshop 2010, experimental results were provided for comparison with simulations.
    - Summary
      This tutorial has introduced the following STAR-CCM+ features:
    - Bibliography
  - 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.
