## Overview

This project examines the flow around a cylinder using Arbitrary Lagrangian-Eulerian (ALE) and Immersed Boundary Method (IBM) approaches.

## Installation Instructions

### 1. Download Ubuntu

To run this project, you'll need to install Ubuntu. Depending on your Ubuntu version, follow the appropriate instructions at the following link:

- [FOAM Extend 4.1 Installation on Ubuntu](https://openfoamwiki.net/index.php/Installation/Linux/foam-extend-4.1/Ubuntu)

### 2. Install FOAM Extend 4.1 and OpenFOAM 9

After setting up Ubuntu, install FOAM Extend 4.1 and OpenFOAM 9 by following the detailed guide available here:

- [Installation Guide for Ubuntu, OpenFOAM 9, FOAM Extend 4.1, GeochemFoam, and ParaView](https://www.poresoftlab.com/post/how-to-install-ubuntu-openfoam-9-foam-extend-4-1-geochemfoam-and-paraview-on-windows-10)

## Running the IBM Model

1. **Activate FOAM Extend 4.1**: Open a terminal in Ubuntu and activate FOAM Extend 4.1.
2. **Navigate to Your Case Study Directory**: Use the `cd` command to go to the location of your case study files.
3. **Clean Up**: Run the clean command to prepare your environment.
4. **Execute the Run Command**: Start the simulation by executing the run command.
5. **Completed**: Your IBM model should now be running.

## Running the ALE Model

1. **Open Ubuntu**: Start Ubuntu on your machine.
2. **Navigate to Your Case Study Directory**: Use the `cd` command to go to the location of your case study files.
3. **Run the AllRun Command**: Execute the `AllRun` command file to start the ALE model simulation.
4. **Completed**: Your ALE model should now be running.
