In keeping with the April/October bi-annual release schedule, the next major version of Caelus, 6.10, was released today. We’ll continue to stick to bi-annual releases until at least 7.04 in April of 2017. Efforts continue to be put toward robustness and performance, with attention directed toward the linear solvers in this release. The new preconditioners/smoother are considerably more robust and yield about a 15-25% performance improvement over the existing ones. Here’s a brief list:

• New symmetric smoother and preconditioner: SSGS
• New non-symmstric smoother and preconditioner: USGS
• General stability improvements for GAMG solver
• No slip wall boundary condition for vector fields with correct treatment of discretization coefficients
  
• Introduced buffer layer damping for kOmega based models suitable for separated flows
• Curvature correction added to all kOmega based models
• VLES models improved for better consistency in RAS limit
• Added compressible gammaReTheta turbulence model
• Added compressible kOmegaSST DES and DDES models
  
• New pressure correction based SIMPLE solver introduced
• New explicit density based solver with single rotating reference frame body force
• Consistency improvements for density based solvers for LES
• Improved explicit solver convergence reporting

There are a release notes PDF available on the download page with more descriptions. http://www.caelus-cml.com/download/

If you’re not already familiar with Caelus, you can read more about it on the website. Its free and open-source. The file formats are compatible with OpenFOAM but there have been many improvements to it such that it is now moving independently in its own direction.

We are happy to answer questions, technical or otherwise, by opening a thread on CFD-Online or directly through email: caelus@appliedccm.com. Please try not to use both for the same question - either or. If you want to ask questions other than about the release, if you don't mind, please open a new thread with Caelus somewhere in the title.
