Fluent Automation Tool

Overview

This project is a Python-based automation tool for running complete Ansys Fluent simulations, designed using object-oriented programming principles. It automates the full pipeline — from geometry import and meshing to solver setup and post-processing — with minimal manual input.

---

Environment and Dependencies

This project was developed and tested with the following software versions:

• ANSYS Fluent: 2025 R1 (Student Edition)
• PyFluent: ansys-fluent-core==0.30.3
• Python: 3.11.3
• Operating System: Windows 11

---

Why This Project

Traditional simulation workflows in Ansys Fluent are GUI-driven and time-consuming. This tool replaces repetitive tasks with clean, modular Python code that improves:

• Productivity through full automation
• Reproducibility by eliminating manual clicks
• Code quality via object-oriented structure and separation of concerns

It reflects a strong combination of engineering domain knowledge and modern software development practices.

Features

• Geometry import using PyFluent API
• Automated watertight meshing workflow
• Solver setup with fluid properties, inlet conditions, and gravity
• Post-processing automation: contour plots, vector plots, and plane slices
• Clean OOP structure with reusable, readable classes

Setup & Requirements

Setup Instructions (Windows 11)

It is recommended to use a Python virtual environment to keep dependencies isolated and organized.

Step 1: Create a Virtual Environment

Open a terminal (Command Prompt or PowerShell) and run:

python -m venv pyfluent-env

Step 2: Activate the Environment

Open a terminal (Command Prompt or PowerShell) and run:

python -m venv pyfluent-env
.\pyfluent-env\Scripts\activate

You should see the environment name ((pyfluent-env)) appear at the beginning of your terminal prompt.

Step 3: Install Dependencies

Make sure you have a working Fluent installation and Python environment with ansys.fluent.core:

1. install ansys-fluent-core

pip install ansys-fluent-core

2. Directory Structure

fluent-automation-tool/

• geometry/
• Static Mixer geometry.dsco
• velocity.png
• temperature.png
• ...
• main.py
• README.md

3. Run the Script

Inside your virtual environment:

py .\fluent_automation.py
