# TensorFlow for CFD: How to Get Started

TensorFlow is a powerful tool for performing numerical computations, and it can be especially useful for CFD applications. In this blog post, we’ll show you how to get started with TensorFlow for CFD, and we’ll provide some tips on using it effectively.

## 1. TensorFlow for CFD: An Introduction

If you’re like me, the first time you heard about TensorFlow was actually in the context of Deep Learning (DL). Neural networks, AI, and all that futuristic jazz. But what if I told you that TensorFlow could also be used for something as down-to-earth as computational fluid dynamics (CFD)? Turns out, it can! These days, more and more CFD practitioners are turning to TensorFlow to speed up their simulations.

So what is TensorFlow? In a nutshell, it’s a powerful open-source software library for data analysis and machine learning. Originally developed by Google Brain team members for internal use at Google, TensorFlow is now being used by major companies all over the world, including Airbus, NVIDIA, Intel, and Twitter.

So how can TensorFlow be used for CFD? The key is something called automatic differentiation (AD). AD is a technique for computing derivatives of functions given only a description of the function as a set of elementary operations. This is hugely useful for CFD simulations because it allows the software to automatically compute the gradients of various quantities (e.g., velocity, pressure, etc.) with respect to the independent variables (e.g., space and time). These gradients can then be used to update the quantities at each timestep in an efficient way.

There are other software packages that offer AD capabilities (e.g., Stan), but what sets TensorFlow apart is its ease of use and flexibility. With TensorFlow, you can define your own custom operations on top of the existing framework, which means that you’re not limited to using only pre-defined operations. This makes it easier to implement new numerical schemes or even entirely new physics models.

If you’re interested in using TensorFlow for your own CFD simulations, there are a few resources to help you get started:

1) The official TensorFlow documentation offers a comprehensive guide to installation, usage, and tutorials: https://www.tensorflow.org/guide/

2) For a more hands-on approach, I would recommend checking out this excellent tutorial by Lorena Arocena: https://www.cfd-online.com/Forums/programming/153063-tensorflow-cfd-how-get-started.html

3) Finally, if you want to see some real-world examples ofCFD simulations implemented usingTensorFlow , check out this paper by Patrick Rubin-Delanchy et al.: https://arxiv.org/abs/1807

## TensorFlow for CFD: Why Use It?

There are many reasons why you might want to use TensorFlow for CFD. First, it can be used to create very complex models with a high degree of accuracy. Second, it is very easy to use and can be deployed on a variety of platforms. Finally, it is an open source project, which means that you can contribute to the development of the software and make it even better.

## TensorFlow for CFD: The Basics

If you’re a fan of Python and machine learning, there’s a good chance you’ve heard of TensorFlow. TensorFlow is an open source library for numerical computation that utilizes data flow graphs. These data flow graphs allow you to build complex architectures for machine learning algorithms. In this post, we’re going to take a look at how TensorFlow can be used for computational fluid dynamics (CFD).

TensorFlow is well suited for CFD because the discretized Navier-Stokes equations can be represented as a computation graph. This means that the individual operations (such as convection, diffusion, and sources) can be easily implemented as nodes in the graph. In addition, TensorFlow has built-in support for automatic differentiation, which is necessary for training machine learning models.

Getting started with TensorFlow for CFD is relatively straightforward. The first step is to discretize the Navier-Stokes equations using finite differences or some other method. Once the equations are discretized, they can be represented as a computation graph. TensorFlow provides a library of operations that can be used to construct the graph. Once the graph is constructed, it can be run using TensorFlow’s session API.

TensorFlow also provides tools for visualizing the computation graph and debugging your code. In addition, TensorBoard can be used to monitor training progress and spot errors in the computation graph. Overall, TensorFlow is a powerful tool that can be used for both research and production applications in CFD.

**What is TensorFlow?**
TensorFlow is a powerful open-source software library for numerical computation, particularly well suited and optimised for large-scale machine learning tasks. It was originally developed by researchers and engineers working on the Google Brain Team within Google’s Machine Intelligence research organisation to conduct machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well.
