OpenFoam is a great open source software for the numerical simulation of water, air, heat and any other physical fluid. Unfortunately OpenFOAM is Linux native and options to run it on Windows are limited with restrictions on tools, versions and available computational resources. With the latest developments on Windows 10 is is posible to install OpenFoam directly in Windows with something called a Windows Subsystem for Linux (WSL) and installing Ubuntu inside Windows.

This tutorial covers all the step required to install OpenFOAM in Windows 10 and its the base for coming modeling tutorials on OpenFOAM.
