(NEWPORT BEACH, CA, 18 September 2019) - MSC Software Corporation (MSC),  a global leader in computer-aided engineering (CAE) simulation software and services, today demonstrated some of the complex multi-physics associated with rugby ball goal kicks inside stadiums.

The quadrennial Rugby World Cup starts in Tokyo on the 20th September and is the third largest sporting event in the world after the Olympics and the Soccer World Cup. This year sees twenty rugby union nations from around the world compete for the ninth time to lift the prestigious Webb Ellis Trophy with the tournament being held in Japan and Asia for the first time until the 2nd November.

Like many sports, debate rages concerning the physics associated with cutting edge sporting performance. Whether it's dimples to improve grip of the ball, or swirling winds inside the stadium, there's a lot of strong opinions. This is particularly true where Rugby balls are concerned. With its characteristic oblong shape and dimpled surface, rugby balls are susceptible to atmospheric conditions and kicking is a skill mastered by elite players.

When swirling winds are coupled with spinning ball aerodynamics inside a stadium, free kick accuracy can make the difference in close games. Being based in Japan, MSC Software's engineers used Cradle's market leading multi-physics focused CFD technology that couples with MSC Nastran and Marc non-linear finite element structural analysis simulation to co-simulate complex rugby free kick scenarios inside stadiums, even including the effect of the ball bouncing off the rugby poles.

"Open roof stadiums are notorious for having cross flows and complex swirling wind conditions that can definitely affect the trajectory of the kicks", said Keith Perrin, Industry lead for Hexagon Software, "Some fans even pride themselves on the local knowledge their teams have about these conditions. Our unique co-simulation software provides a deep understanding of the fundamental fluids and structural mechanics affecting the ball, and their inevitable interaction in a game. In this case the interaction of air flow, ball rotation, and ball deformation can all be taken into account.

Whatever happens in the next month or so, and irrespective of all the debate, we wish all teams well in the tournament, and many successful free kicks!"
