DISPL1; 1- and 2-dimensional kinetics-diffusion partial differential equations solution. [IBM370/195,303x; CDC7600,6600,CYBER175; MORTRAN2 (80%) and FORTRAN (20%)]

Technical Report ·
OSTI ID:6369017
DISPL1 is a software package for solving second-order nonlinear systems of partial differential equations including parabolic, elliptic, hyperbolic, and some mixed types. The package is designed primarily for chemical kinetics-diffusion problems, although not limited to these problems. Fairly general nonlinear boundary conditions are allowed as well as interface conditions for problems in an inhomogeneous medium. The spatial domain is one- or two-dimensional with rectangular Cartesian, cylindrical, or spherical (in one dimension only) geometry.IBM370/195,303x;CDC7600,6600,CYBER175; MORTRAN2 (80%) and FORTRAN (20%). By use of the MORTRAN2 preprocessor %F control card, the FORTRAN component is passed through the MORTRAN2 preprocessor along with the MORTRAN component.; OS/370 (IBM370/195,3033), SCOPE 2.1.3 (CDC7600), SCOPE 3.4.4 (CDC6600), NOS1.3 (CDC CYBER175); The IBM version DISPL1 source requires 600K bytes of storage for compilation. Compilation and execution of the DISPL1 sample problems, including the plot creation jobs, requires a maximum of 350K bytes. The CDC version requires a maximum of 121,000 (octal) words of executable storage for the CDC7600, 140,000 (octal) words for the CDC6600, and 135,000 (octal) words for the CYBER175 execution. In the MORTRAN2 preprocessing stage, the user can easily adjust the storage requirements to the optimum for a current problem. In addition to the standard input and print files, the program requires files assigned to logical unit 10 for reading restart data, logical unit 11 for writing data for a later restart, and logical unit 12 for writing plotting data.
