How to calculate penetration depth of a rigid body impinging in water?
Hi,
I am working on Numerical Analysis of rigid body impinging in water using Ansys Fluent in which I have to calculate penetration depth of that body in the water. I am unable to do that kindly help me regarding that. Thanks & Regards! |

You can plot a report definition for the minimum Z value of body. This will create a plot of the bottom edge of the body over time. If you know the level of the water then you can calculate how far the body penetrates. I would recommend drafting your domain with the water level at 0. Then, from you plot, the minimum value it achieves will be the penetration depth. |

Can you please tell me from scratch or if possible please make a video on this? |

Could you provide some images of your domain as well as the boundary conditions such as the size and speed of the sphere? |

I used a dynamic mesh where I took only The body as the component zone and considered it as a rigid body only, mapped it with the mass of the object 19kg and took One degree of translation, and put the "y" value as 1. And did the hybrid initialization and patched it. I have taken two phases 1st is air and second is water. |

I have taken the body as a component zone and the domain as the background zone. All the walls of the domain I took as walls-background except the upper wall. For the upper face wall, I have taken the "specified pressure zone," which I gave as pressure inlet (Atmospheric pressure), as you can see in the screenshots. |

Yes, I am using VOF. And I am attaching screenshots of all the steps I took in the setup part numbered in sequence. Kindly look at that.
