Open Source: A Philosophy Behind SimScale

Open Source: A Philosophy Behind SimScale simulation platform - landing gear

Engineers using the SimScale platform interact only with the user interface for their daily simulations. However, out of either curiosity or security concerns, some of them frequently ask us about the simulation codes we are currently using in the background. Definitely this is not a commercial secret, and we would like to share it with you. On the website you can find information about application tools for solving, meshing, and visualizing.

Reinforcing Open Source

As many professional users expect, one of the philosophies behind SimScale is the integration and reinforcement of Open Source Code (download this fact sheet to learn more). Worldwide, open-source users volunteer to improve the codes, which are being gradually maintained and developed with a high level of adequacy, accuracy, and transparency.

We sincerely appreciate all the contributors to Open Source Codes, with whom each update of the SimScale platform with new features is made possible.

In fact, the applications of Open Source Codes are quite common nowadays. Some well-known software examples of successful implementations of Open Source projects could be:

  • Android, the world’s leading smart-phone platform;
  • Wikipedia, the biggest free encyclopedia;
  • Darwin, the kernel of Mac OS X;
  • Mozilla Firefox.

Today I want to introduce you to one of our most used software codes:

OpenFOAM® is a toolbox for dealing with complex CFD problems. It contains a wide range of physical models (including turbulence, wall treatment, thermodynamics and mass transport), numerical methods and tools for pre- and post-processing. Originally developed at the Imperial College London, OpenFOAM® offers impressive accuracy and is extensively validated in academic and industrial environments. It is being continuously developed and expanded by a large community of scientists, experts and industrial customers, ensuring rapid implementation of new technologies. As a result, OpenFOAM® was recently able to oust commercial codes for various industries, including Automotive.

Extremely popular worldwide, OpenFOAM® is being used by leading companies for various applications and different industries. The following are just a few of them:

  • Volkswagen Group
  • BMW AG
  • Ford Motor Company
  • Airbus S.A. S.
  • Siemens AG General
  • Electric Corporation
