Surface grid and pressure contours on a F/A-18C. The geometry consists of a F/A-18C aircraft with AIM9 missile and rail, 330 gallon tank mounted below the inboard pylon, and a JDAM/MK-84 mounted below the outboard pylon. The grid consists of 8 zones, with approximately 1.5 million cells. The solution was obtained utilizing 64 SGI R10000 processors, and required approximately 4 1/2 hours to converge five orders.
