FLUENTwill compile the code and show the progress in the console. A Warning dialog box will open asking you to make sure that the UDF source files are in the same folder that contains the case and data files. Select the source file, 6dof 2d.c and click OK. button in the Source Files section to open the Select File panel. Step 3: Compile the UDF Define User-Defined Functions Compiled Click the Add. Enable the standard k-ɛ turbulence model. (e) Click OK to close the Multiphase Model panel. (d) Enable Implicit Body Force formulation. (c) Retain the default settings for VOF Scheme and Courant Number. (a) Select Volume of Fluid from the Model list. (c) Select the Green-Gauss Node Based option from the Gradient Option list.

October 12, 2006ģ Setup and Solution Step 1: Grid 1. Create a subfolder named tiff-files to store the tiff files created for postprocessing purposes. Copy the files, and 6dof 2d.c to your working folder. October 12,Ģ Figure 1: Schematic of the Problem Preparation 1. Whenever the box and its surrounding boundary layer mesh are displaced, the mesh outside of the boundary layer will be smoothed and/or remeshed.
The walls of the box undergo a rigid body motion and will displace according to the calculation performed by the 6DOF solver. When the box is immersed in water, it is also subjected to a buoyancy force. The box is subjected to a viscous drag force and a gravitational force. A box is dropped into the water at time t = 0. Problem Description The schematic of the problem is shown in Figure 1. Some basic steps in the setup and solution procedure will not be shown explicitly.
Prerequisites This tutorial assumes that you are familiar with the menu structure in FLUENT and that you have a good understanding of the basic setup and solution procedures. Create TIFF files for graphic visualization of the solution. Use the VOF multiphase model to model the buoyancy force experienced by the moving body.

This tutorial demonstrates how to do the following: Use the 6DOF solver to calculate motion of the moving body. Gravity and the bouyancy forces drive the motion of the body and the dynamic mesh. The 6DOF UDF is used to calculate the motion of the moving body which also experiences a buoyancy force as it hits the water (modeled using the VOF model). 1 Introduction The purpose of this tutorial is to provide guidelines and recommendations for setting up and solving a dynamic mesh (DM) case along with the six degree of freedom (6DOF) solver and the volume of fluid (VOF) multiphase model.
