This directory contains the sequential C version of the fortran cfd codes - appbt and appsp - written at NASA Ames Research Center by Sisira Weeratunga. These codes were converted to C by a team of students for their class project for CS 838-3/ChE 562 offered in Spring 1993 by Mark D. Hill, Sangtae Kim, and Mary Vernon at the University of Wisconsin at Madison. CS 838-3/ChE 562 was an experimental course that brought computer scientists and computation scientists together to promote interdisciplinary research. You should have a NAS license for the original fortran code. NASA has given us permission to distribute our ``significant'' changes freely. You can obtain the sequential fortran codes and a license by writing to: ATTN: NAS Parallel Benchmark Codes NAS Systems Division Mail Stop 2588 NASA Ames Research Center Moffett Field CA 94035 THIS SOFTWARE IS PROVIDED "AS IS".
