(60fps) Getting started: Dropping object into water using Overset mesh in Ansys Fluent

Basic introductory Computational Fluid Dynamics (CFD) simulation tutorial using Ansys
1. Creating 2 separate bodies in SpaceClaim with named selections
2. Deleting contacts in Ansys Meshing and generating separate meshes
3. Generating overset interface and assigning dynamic mesh zones in Ansys Fluent, mass and moment of inertia specified using a UDF
4. Running a transient 2D multiphase flow simulation

How to solve floating point exception?

How can i plot displacement of rigid body vs time step graph?

[@deepankaryadav84]

Can you tell me about your udf means what mass in units u have taken and where is Ixx Iyy and only Izz taken and what other parameters.

What about that warning appeared? "overset connectivity information is only written to case files in ansys common fluids format (cff). it is recommended that you write overset cases in cff format." This actually collapse my simulation in 3D.

can you tell me what is the unit of mass he has taken and unit of Izz

Hi, Do you know if it is possible to change the boundary conditions of the overset or change the udf in such a way that the overset moves along with an imposed flow on the background grid?
