LS-DYNA Simulation White Paper

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.

You'll learn about:

Performance
comparison of fan
blade off simulation in
LS-DYNA R8.0.0 and
R7.1.2

LS-DYNA code
optimization for fan
blade off simulation on
the Cray XC40 system

MPI communication time
and synchronization time


In a real-life simulation, an explosive charge is fired to release the turbine blade, leaving very little visible detail in the engine. LS-DYNA’s simulation visualization allows engineers to strip away part of the structure to see those details, and alter their design if necessary.
