Trantham, Jr, F M

Two new versions of the CURE Code designed to take advantage of the 32,000 word machine are given. The original CURE Code, made available in June 1957, was for an 8000 word, 6-tape IBM 504 and handled 644 collapsed mesh points. The first of the two new versions utilizes the additional core memory to quintuple the number of mesh points allowable. It will handle from 1 to 50 groups. The second of the two new versions utilizes the additional core memory to double the number of mesh points allowance, reduce (from 6 to 3) the number of tape units required, approximately halve the running time per power (outer) iteration and reduce tape errors to the vanishing point. It will handle from 1 to 3 groups. Both versions incorporate a number of refinements not present in the original code. Also, both versions incorporate the Shinn version of the Peaceman-Rachford flux iteration block that is estimated to run approximately 16% faster than the original version. (auth)
