Improving aerospace engine simulation
Cray and LSTC speed up a critical simulation involving over 80 million elements
Among the critical simulations aerospace manufacturers must run is fan blade off, which simulates the failure of a fan or compressor blade in a jet engine at high rotating speeds. Building a prototype engine for the required certification test — which destroys the prototype — runs into millions of dollars, so simulation is a fundamental cost- and time-saving step in the design process.
It’s also technically challenging and computationally intensive, typically involving tens of millions of elements and requiring more than a month to complete. But a team from Cray, LSTC and Rolls-Royce Corp. successfully ran a fan blade off simulation involving more than 80 million elements in 21 hours.
This free white paper details the use of LS-DYNA, a finite element program developed by LSTC, on a Cray® XC™ supercomputer to simulate fan blade off containment.
