Three-dimensional, unsteady, multi-zoned fluid dynamics simulations over full scale aircraft is typical of problems being computed at NASA Ames' Numerical Aerodynamic Simulation (NAS) facility on CRAY2 and CRAY-YMP supercomputers. With multiple processor workstations available in the 10-30 Mflop range, we feel that these new developments in scientific(More)
Using leaf epidermis from Vicia faba, we tested whether auxin-induced stomatal opening was initiated by auxin-induced ethylene synthesis. Epidermis was dark-incubated in buffered KNO3 containing 0.1 mM alpha-napthalene acetic acid or 1 mM indole-3-acetic acid. Maximum net opening was ca. 4 micron after 6 h. Opening was reversed by 20 microM ABA, 0.1 mM(More)
Tools specifically oriented toward flow analysis problems are described. The approach is oriented toward performing graphics calculations on the supercomputer and using high-end workstations as rendering engines to display flow fields generated by aircraft flight. A suite of software provides both display and interactive analysis capability. Also described(More)
<italic>Recent advances in computer graphics hardware and software have resulted in major improvements in our ability to experience computer simulations of physics by viewing dynamic three-dimensional scenes representing the simulations. This paper describes the hardware and software tools and techniques in use at NASA's Numerical Aerodynamic Simulation(More)
