This manual describes the first release of GRIZZLY, a computer program to construct tables of atomic data for use in applications programs The first release of GRIZZLY has the capability to generate baseline equation-of-state tables for elements and mixtures using various physical models GRIZZLY runs on the Los Alamos CRAY-1 computers I INTRODUCTION In the past a total it was usually equation-of-state (EOS) cumbersome and time consuming It has become apparent that program the would GRIZZLY is porated 7) into the The physical latest models that models data if base properties because development thoughput such a calculation of decentralization of an automated for producing in EOS theory, but of material tables Future calculated properties such as opacity a baseline models plans release they represent to generate more sophisticated desired hydrodynamics used in the first may be used provide use Hence, are used in various EOS In the meantime, for table to calculate was often and data interfacing and centralized EOS tables computer The purpose of such a capability EOS tables are collected and incor1-3 SESAMEdata library which can be accessed by several code which be the will improve to run more than one code to provide 4-6 packages necessary for capable programs Also planned and conductivity is Ref intended computationally dependable producing by newer models GRIZZLY also example, of GRIZZLY are not EOS Future of (for releases of a higher GRIZZLY quality may be read into include the development the computation of to GRIZZLY of a transport GRIZZLY allows the users contributions calculate produce tables; perform table density scaling, to operations, specify data to be used in calculating display input read execute in various tables from (to) are GRIZZLY is a table tables or perform initiated number in oriented operations this of are called subroutines programs via code provides user of evaluate comands directly These commands from the users

schemes; data and calculated procedures through models etc.; using (write) on physical combining terminal from i.e., mix tables may be read of the EOS based Items page to models a common input scavenged These base Most from existing used by GRIZZLY have been extracted EOSCRAY8 and PANDA.9 The Thomas-Fermi-Dirac (TFD) model for has been extracted from CANDIDE.10 The ideal mixture 11 from MIXB Models can be evaluated either individually electronic excitations scheme has been taken or multifunction procedures supplied compression tables12 are easily All modified based the on material to various EOS with and temperature obtained because grids users relative such data data specification and tabulated models are tabulated default user of or user equation-of-state individually values

are evaluated data used by GRIZZLY are assigned by issuing Every Models as part should to use in order be able to generate to appeal a baseline ease EOS tables Tables may be written may also to SESAMEfiles be read and written for use in programs in GRIZZLY data base formatted files tables or thermodynamic functions are written 13 which may be read by CURVES to provide a graphics interface to files Not all All displays of of GRIZZLY has been adapted of GRIZZLY which are associated with from other items codes through In fact, represent the portions new code devel- opment Table variable I-2

GRZDBmay be the command MASS GET DIR=/LTE GRIZ GRZDB GRIZZLY may be executed GRIZ I = iname, using the CTSS execute line P = pname, E = ename / t p The name of iname is If I If the terminal command,
