OpenFOAM Email This Post Print This Post


The OpenFOAM (Open Field Operation and Manipulation) is an open source CFD toolbox produced by OpenCFD Ltd from UK. It can simulate anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics, electromagnetics and the pricing of financial options.

The core technology of OpenFOAM is a flexible set of efficient C++ modules. These are used to build a wealth of: solvers, to simulate specific problems in engineering mechanics; utilities, to perform pre- and post-processing tasks ranging from simple data manipulations to visualisation and mesh processing; libraries, to create toolboxes that are accessible to the solvers/utilities, such as libraries of physical models.

Simulating dynamic tanks in EMSO (Part 1) Email This Post Print This Post

This post starts to our section of HOW-TO texts. My objetive with this specific post is to introduce using some free tools to different applications.

A classic problem in process engineering is the case of a dynamic tank where the output flow is proportional to its level (Fig. 1). This example is part of EMSO tutorial so that more details would be to consult in the EMSO manual.

In this approaching, the problem of dynamic tank involves 3 variables and 2 parameters such below:

Sim42 Email This Post Print This Post

Simulator42 is an open source process simulator project with the goal of providing an affordable and accessible chemical process simulator to the chemical engineering community.

Some interesting features of the project:

  • It is being written in the Python language.
  • The simulator core has been designed to be independent of both user interfaces and thermo providers.
