CALNPS: Computer Analysis Language Naval Postgraduate School Version

Abstract

The Computer Analysis Language (CAL) Program was originally written by Professor Edward L. Wilson of the University of California at Berkeley as a teaching tool for structural analysis. The program was modified for use on the Naval Postgraduate School (NPS) mainframe (IBM 360/67) in 1979 by Lawrence B. Elliott, Lieutenant Commander, U.S.N. The modified version was called CALNPS. In 1982, Warren L. Roberts, Lieutenant, U.S.N., integrated the Finite Element Analysis Program (FEAP) with CALNPS. This provided a means for the solution of linear and nonlinear, two and three dimensional, and, steady state and transient heat conduction problems. Roberts also generated an interactive HELP facility and the code for terminal graphics displays of heat transfer and structural analysis meshes. Since then, changes to the NPS computer system and transition of CALNPS to the VAX computer system have rendered CALNPS unusable in many ways. The HELP facility is obsolete. The purpose of this thesis was to bring CALNPS back up to date, rewrite the HELP facility, and make the program user friendly. Also several modifications were added to CALNPS. The graphics capabilities were expanded to include hardcopy options using the Plot 10 and Display graphics libraries. Two display size options are now available and the user now has the capability to plot curves from data files from within the CALNPS domain.
