The output of make should look similar to the content of the code box below. The simpleMLP example in the repository mentioned above contains the implementation of a simple neural network in LibTorch and a CMake configuration file that enables verbose output during the compilation. Instead of checking all the CMake files contained in LibTorch, I found it much easier to simply look at the final compile command created by CMake and then to add PyTorch-related options to the wmake options file.

This repository currently contains two examples and instructions on how to run them: I decided some time ago for the latter approach and haven’t changed my workflow since then. Therefore, you are confronted with the following dilemma: you can either try to figure out how to compile OpenFOAM apps with CMake or you learn how to build LibTorch programs with wmake. In contrast, OpenFOAM applications are typically compiled using wmake. $ Compiling examples using wmake and CMakeīy default, LibTorch applications are compiled using CMake, and dependencies are defined in CMakeLists.txt files.

RUN apt-get update & apt-get install -no-install-recommends -y \Įcho ". # some commands to install required packagesĪRG FOAM_PATH=/usr/lib/openfoam/openfoam2006 Here, I only want to focus on some of the details. The Dockerfile and instructions on how to build and use an image can be found in this repository (I try to keep it up to date with the current versions of PyTorch and OpenFOAM). PyTorch 1.6 pre-compiled C++ API package (LibTorch).OpenFOAM-v2006 pre-compiled Debian/Ubuntu package by ESI-OpenCFD.So here is how to create a Docker image based on: If you’re not much of a Docker user, you should still read this section because it also explains some details needed for local installations.

If you have read some of my previous blog posts, you know that I am a fan of software containers as a means to make workflows reproducible and shareable ( read more). If you had a different experience with Tensorflow or PyTorch, let me know! I would love to see workflows that make it as easy as possible for users and developers to switch between both frameworks according to their needs. Of course, these arguments only capture my current impression, and DL frameworks are improving at lightning speed.

Both PyTorch and Tensorflow provide C++ and Python frontend APIs. Why should you consider using PyTorch instead of Tensorflow/Keras? The short answer is because PyTorch is easy and fast. So let’s skip the prose and get started with the nitty-gritty of this article: how to set up PyTorch to run DL models in OpenFOAM apps. If you found your way to this article, chances are high that you don’t need to be convinced of the potential of ML/DL + CFD. In the field of machine learning (ML) applied to CFD, deep learning (DL) algorithms allow us to tackle high-dimensional problems more effectively and promise significant progress in fields like turbulence modeling, flow control, or shape optimization. The main idea is to use available datasets to make simulation-based workflows faster or more accurate. Incorporating data-driven workflows in computational fluid dynamics (CFD) is currently a hot topic, and it will undoubtedly gain even more traction over the months and years to come.
