Ansys claims CFD record.
ANSYS has claimed a new record with its simulation software.
The company said its computational fluid dynamics (CFD) software had been used to run a single mesh with more than a billion computation cells, the first time a commercial package had achieved such a high degree of accuracy.
The milestone was reached by an Italian engineering team investigating the aerodynamics of a yacht for the Luna Rossa Challenge entry in the America's Cup race.
Dr Ignazio MariaViola, who led the engineering team, said: "Our research indicates that this is among the world's first applied engineering simulations using a single mesh of more than one billion cells performed with commercial software.
"The possibilities for engineering simulation using high-performance computing are massive, and I'm sure we will see groundbreaking design developments."
Computational cells are an integral part of CFD simulations. When conducting a simulation, computers break down the surface area and/or volume of a design into cells. These form the basis for a series of equations that model the fluid flow or stress on a design. The higher the cell count, the more detailed a simulation.
According to Ansys, the simulation of a racing yacht was difficult because of the combination of hydrodynamic and aerodynamic flows and the stiffness of the yacht. The one billion cell-plus simulation focused on the aerodynamic impact of wind on the vessel sailing downwind, with emphasis on the mainsail and an asymmetrical spinnaker.
