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®
  • Anyone who is interested in parametric modeling for more complex free-form surfaces

Upfront CADService Required?

You don’t have the time in your daily business to create geometry with CAESES® Free,  but it would be great to have such a simulation-ready and variable geometry available? Simply ask us! We offer a quick and professional service to create tailored parametric models for you. Just give us your input (dimensions, design parameters, constraints, reference geometry etc.) plus a couple of days. Use such a custom model either with CAESES® Free without any additional costs, or together with our pro-edition to readily conduct automated design studies and formal shape optimizations.
