AN APPROACH TO FLUID MECHANICS CALCULATIONS ON SERIAL AND PARALLEL COMPUTER ARCHITECTURES

SUMMARY The T ransient R eactor A nalysis C ode (TRAC) is a large FORTRAN thermal-hydraulics program designed to solve problems involving internal flows in nuclear reactors. The current versions have been designed for a CDC 7600 and CRAY 1 but benchmarks have been run in parallel simulations. This paper will discuss the methods in use, the reason that these techniques are effective, and their extension to parallel machines.
