10. Unsteady Aerodynamic Simulation Dynamic Ground Effect:
Unsteady simulation of entire landing sequence of a high lift wing
Problem size: 36 Million volume grid & simulation of 11 secs of
the landing sequence System : 8 days on XC40 using 10000 Xeon cores
(for a time step of .001 sec)
11. Observation: A critical number of supernovae required to
maintain an over-pressured bubble for 10s of Myr, for a given
density and spatial separation between supernovae. These
superbubbles should break out of galaxies and suppress global star
formation. PLUTO hydrodynamics code to simulate supernovae using
5123 and 10243 simulations. Application scales upto 12,000 cores.
