CAESES® Free is a free version of the commercial CFD integration platform CAESES which has been developed for simulation-driven design of flow-exposed surfaces. It offers comprehensive parametric CAD functionality, CFD integration and post-processing features. Feel free to use this edition even for commercial work without any limitation!



Who should use CAESES® Free?

With this piece of software we address

  • Users of both open source and commercial CFD codes to bridge the gap between geometric modeling, geometry variation and CFD analysis
  • Developers of CFD tools and researchers in fluid dynamics to use CAESES® Free as their front end for code validation, result comparison and parametric studies of CFD settings and design variants
  • CFD consultants to utilize CAESES® Free as a convenient environment to showcase the product improvements they could achieve
  • CFD users to accelerate their CFD preprocessing tasks
  • Entrepreneurs to generate new business by developing parametric models, optimization set ups and automation features and, thus, position themselves as consultants to users of the pro edition CAESES/FFW
  • Anyone who is interested in parametric modeling for more complex free-form surfaces

Why is it free?

CAESES® Free is a scaled-down version of CAESES, which helps us to collect a lot of amazing feedback. With this, we are able to continuously improve our products, and bring the spirit of simulation-driven design to a broader community. CAESES® Free allows you to set up innovative smart paramatric models, and based on such a model you can even generate up to 5 design variants per project, either manually or fully automated. This might give you a taste of the pro edition, which comes with unlimited automation and premium customer support.

Note that CAESES® Free project files (*.fdbc) cannot be opened in the pro edition CAESES – we offer a file conversion automatism for this purpose. For more information just get in touch with us.
