Welcome to the polyhedral revolution

VETA is pleased to announce the release of the world's first fully integrated process for polyhedral CFD. The first official release of the STAR-CCM+/Design combines CD-adapco's technology leading STAR-CCM+ solver with STAR-Design, which includes the world's first commercially available polyhedral mesher.

STAR-Design, CD-adapco's fully functional parametric solid modeler, allows polyhedral meshes to be created at the click of a button. Based on the same Parasolid kernel that powers many leading CAD packages, STAR-Design is both powerful and easily accessible. Using an intuitive interface, even a casual user can build, mesh and run an industrial strength CFD simulation. Using STAR-Design, polyhedral meshes can be automatically generated from the created (or imported) CAD geometry at the click of a button.

Extensive validation has demonstrated that polyhedral meshes offer near hexahedral accuracy with all the automatic meshing benefits of tetrahedra. Professor Milovan Peric, CD-adapco's Director of Technology, explains, “Recent tests have shown that, for equivalent or better accuracy, polyhedral meshes converge up to ten times faster than tetrahedra, typically delivering a speedup of 400 - 500%”, he says, "Polyhedral CFD delivers more for less: more accurate solutions, using fewer cells and ultimately greatly reduced human and computing resources. We also have seven years of experiece with polyhedral meshing and lead our competors by at least five years."

Dr Dennis Nagy, CD-adapco's Vice President of Business Development, acknowledges that polyhedral meshing is the first payoff of CD-adapco's investment in solver technology. "While other CFD vendors are content to simply build upon their existing aging software architectures, with STAR-CCM+, we decided to go back to the drawing-board and build our solutions upon the most advanced technology currently available", says Dennis. “The arrival of polyhedral meshing represents a watershed for industrial CFD".

" I am confident that the arrival of our polyhedral meshing technology spells the end for tetrahedra as a useful tool for CFD", says CD-adapco President Steve MacDonald. "Tetrahedra - as well as the CFD codes which continue to rely on them - are doomed to become a thing of the past"
