Installing OpenFOAM-12 on Ubuntu and Windows
We are suggesting two methods for installing OpenFOAM-12 on ubuntu and windows: 1) source pack and 2) pre-built files. If you already have some components installed on your computer, you may skip some of the steps. This method has been tested on Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu…
Meshing a Cylinder Using blockMesh
Use this blockMeshDict to automatically create a structured mesh for cylinder given the radius, height and average cellSize for the final mesh. There will be 3 boundary patches for you in the final mesh: inlet, outlet, and cylinerWall. You also have the option to make the inner square curvy-like by…
How to install OpenFOAM on Windows 10 & 11
To get the best experience with OpenFOAM installation on windows, you need to have windows 10 (build 19041 and higher) or higher versions of Windows like windows 11. So, you can install/activate WSL2 on your computer. WSL, stands for windows subsystem for Linux, is a new technology of Microsoft and…
How to install OpenFOAM-9
In this tutorial, you will learn how to install OpenFOAM-9. If you already have some components installed on your computer, you may skip some of the steps. This tutorial has been tested on Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. Two main methods are…
Four: Flow pattern and particle mixing in a rotating drum using DEM
We investigate mixing mechanism in a rotating drum operating in rolling regime. To this end, a drum with the diameter of 0.2 m and depth of 0.03 m is half-filled with 19000 3-mm spherical particles. Rotation speed of the drum is 10 RPM. This rotation speed creates the cascading regime…
Methane Combustion in a Flare
Excess, unrecoverable hydrocarbons are collected and burnt (in a flare) before releasing to atmosphere to reduce their environmental impact. Millions tones of hydrocarbons are burnt each year all around the world. A survey shows that, in 2017, around 270 million tones of CO2 is emitted by flaring. In many industrial…
How to Install OpenFOAM v2012 from Source Pack on Ubuntu
In this post you will learn how to install OpenFOAM v2012 from source pack. The procedure is tested on Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. It is assumed that you are installing OpenFOAM v2012 on a fresh operating system. Note1: If you previously installed the older version of OpenFOAM…
Three: Flow pattern of particles in the discharge of a conical hopper using DEM
The flow of spherical particles in a conical hopper with the cone angle 45° is studied using DEM. Density and size of particles are 2500 kg/m3 and 9 mm, respectively. Diameter of the conical hopper is 20 cm and diameter of the exit orifice is 8 cm. A wide, flat…
Two: A DEM simulation to create a random packed bed of spheres with size distribution
In this DEM simulation, we create a random packed bed of spherical particles in a cylindrical container with the diameter of 15 cm and height of 20 cm. Particles are a mixture of spherical particles with similar density (2500 kg/m3) and uniform sizes distribution between 3 and 7.5 mm. In…
