CD Adapco has released what it claims to be the world's first fully integrated process for polyhedral computational fluid dynamics.
CD Adapco has released what it claims to be the world's first fully integrated process for polyhedral computational fluid dynamics.
The first official release of the Star-CCM+ Box Set 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 modeller, 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 easily build, mesh and run an industrial strength CFD simulation.
Using Star-Design, polyhedral meshes can be easily 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 of 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".
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 on their existing aging software architectures with Star-CCM+, we decided to go back to the drawing-board and build our solutions on the most advanced technology currently available", says Dr Nagy.
"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 and founder Steve MacDonald.
"Tetrahedra - as well as the CFD codes which continue to rely on them - are doomed to become a thing of the past".
The Star-CCM+ Virtual Box Set is available to existing CD Adapco customers from the company's website, where potential users can also download a trial version.
