Description
Description
In this project, the movement of the golf ball due to the impact force of 200 Newtons with an angle of 30 degrees has been investigated, and the movement path of the ball has been determined using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The present model is designed in 3-D using the Design modeler. The geometry is related to a golf ball placed inside a domain.
The meshing of this present model has been generated by ICEM software. The total cell number is more than 945765.
Also, due to the nature of the present problem, the transient solver has been enabled.
Golf Methodology
In this project, a golf ball movement with an aerodynamic point of view has been studied. The force which is applied to the ball is equal to 200 N. The golf ball displacement due to the impact has been studied in terms of time.
Therefore, to simulate the free motion of the golf ball within the domain, the Dynamic mesh option has been enabled. Due to this motion, the quality of the mesh cells will deteriorate as time passes.
Thus, the smoothing and remeshing sub-models have been enabled to create high-quality mesh whenever the old mesh quality is not suitable for the continuation of the solution. Also, the six DOF options can model all the possible motion types for the golf ball.
Moreover, the SST k-omega model is used to solve the turbulent fluid flow equations due to its advantage in predicting flow patterns near and far from the surfaces.
Golf Conclusion
After the simulation, two- and three-dimensional contours related to pressure and velocity at different flow times are obtained. For instance, as seen in the pressure contour, the front region where the pressure has increased denotes the stagnation point.
In contrast, the rear part where the pressure has decreased indicates the wake region where the flow is separated from the golf ball’s surface.

Does the simulation also take into account the spin of the golf ball often found in real-life scenarios?
MR CFD Support –
The detailed dynamics of the golf ball, including the effects of spin, would be important for an accurate simulation in golf ball analytics. Unfortunately, the current description does not detail this aspect; however, typically, a golf ball’s movement simulation like this, especially if aimed at mimicking real-life conditions, would incorporate the golf ball’s spin. The six degrees of freedom (DOF) define both linear and angular motion, which suggests that the spin could indeed be considered in the analysis if set up in the solver.

This tutorial seems thorough, but could you tell me more about how the six degrees of freedom (6 DOF) model influences the movement and analysis of the golf ball in the simulation?
MR CFD Support –
Certainly! The six degrees of freedom (6 DOF) model is key in accurately representing the golf ball’s motion. It allows the simulation to account for all possible movements of the ball, including translation in three perpendicular axes and rotation about three perpendicular axes. This holistic approach ensures the simulation captures how the ball responds to the impact, including changes to its flight path and spin, which is critical in evaluating the aerodynamic performance.
Prof. Kelvin Keeling IV –
This tutorial sounds comprehensive, but I’d like to know how the initial conditions were set for the golf ball before the impact. Specifically, was it at rest or in motion, and how is that accounted for in the simulation setup?
MR CFD Support –
The initial conditions for the golf ball in this simulation were determined to consider this factor correctly. The ball is initially modeled as being at rest, and the impact forces are then applied to set it into motion. This setup allows for an accurate analysis of the ball’s movement from the moment of impact.
Prof. Leone Bogan V –
What are the key advantages of using Dynamic Mesh and the six DOF options in the simulation of the golf ball’s movement?
MR CFD Support –
The advantage of using Dynamic Mesh in this golf ball simulation is that it allows the mesh to adeptly adjust as the ball moves through the domain, ensuring accurate calculations as the geometry changes. The six Degrees Of Freedom (DOF) option further enhances the simulation by allowing the ball to move freely in all directions and rotate as it would in a real-world scenario, thus providing a comprehensive understanding of the golf ball’s dynamics post-impact.
Keshaun Trantow –

Lela Klocko –
I was amazed by how the golf ball simulation can show the stagnation and wake regions. What makes the SST k-omega model suitable for this golf ball impact simulation?
MR CFD Support –
The SST k-omega model is particularly suitable for this type of simulation because it effectively captures the flow’s characteristics both near the wall and in the far field. This model combines the robust and accurate formulation of the k-omega model in the near-wall region with the free-stream independence of the k-epsilon model in the far field, making it a good choice for simulations where accurate prediction of flow separation, which often occurs in the wake of objects like a golf ball, is important.
Lydia Corwin –
This looks thorough and interesting! Were real-world conditions like wind and air temperature taken into account for this simulation of the golf ball’s movement or is it based purely on the initial impact force and angle?
MR CFD Support –
In this simulation scenario, the primary variables are the impact force of 200 Newtons and the angle of 30 degrees. Environmental factors such as wind and air temperature have not been explicitly noted, suggesting that this particular simulation focuses on the aerodynamics of the golf ball post-impact. However, realistic environmental conditions can typically be incorporated into these simulations to provide a more comprehensive analysis if required.

Mr. Lamont O’Reilly PhD –
I’m intrigued by the use of the Dynamic Mesh in this simulation, especially the mechanisms of smoothing and remeshing. Can you explain how the quality of the mesh is maintained throughout the golf ball’s motion?
MR CFD Support –
During the CFD simulation of the golf ball’s motion, maintaining the mesh quality is crucial as the ball’s position changes over time. The ‘Dynamic Mesh’ method incorporates ‘Smoothing’ to adjust existing mesh nodes within their element boundaries, enhancing mesh quality without altering the number of cells. ‘Remeshing’ is utilized to regenerate and refine the grid where necessary based on predetermined quality criteria thresholds. This ensures that, regardless of the ball’s motion or deformation of the computational domain, the mesh adapts dynamically, sustaining the solver’s accuracy and stability.
Nedra Rohan –
The dynamic mesh’s smoothing and remeshing sound essential for this simulation. Can you explain how it works?
MR CFD Support –
Sure, dynamic mesh’s smoothing and remeshing are crucial techniques that adapt the mesh as the simulation progresses over time. Smoothing adjusts mesh node positions to prevent poor-quality elements without changing mesh connectivity, while remeshing generates new cells to replace distorted ones. This ensures high-quality mesh throughout the simulation, which is necessary for accurate results in cases like the movement of a golf ball under impact.
Ardella Batz –
Out of curiosity, can this simulation show what would happen if the angle of impact changed or if a different force was applied to the golf ball? It would be intriguing to see how different variables affect the ball’s path.
MR CFD Support –
Absolutely, this simulation has the capability to adjust and analyze various hypothetical scenarios including changes in the angle of the golf ball’s impact or different magnitudes of force applied. By altering these input parameters, one can examine the subsequent effects on the golf ball’s trajectory, speed, and the flow separation patterns around the ball, providing insights into the physics of golf ball aerodynamics. These changes can be explored within the Carbon Dynamic Mesh toolbar Zator options in ANSYS Fluent to observe how the golf ball reacts to different forces or impact angles.

I am thrilled by how the movement of the golf ball was captured! Could you elaborate on how the Dynamic Mesh technique maintains mesh quality during the simulations?
MR CFD Support –
Thank you for your positive feedback! In response to your inquiry, the Dynamic Mesh technique utilizes algorithms designed to adjust the mesh as the golf ball moves. The ‘smoothing’ operation redistributes the mesh points smoothly in motion-affected areas to prevent excessive distortion. Whereas ‘remeshing’ replaces this deteriorated mesh with a new one that can better accommodate the current position and shape of the golf ball, maintaining an optimal mesh quality throughout the simulation.
