This manual describes EOSPAC, a subroutine package for accessing the Los Alamos Sesame equations of state (EOS) data library, EOSPAC is designed for easy implementation in most hydrocodes running on the Los Alamos Cray-1 computers. The Sesame EOS data are in tabular form and are accessed in two phases. During the set-up phase, the requested data tables are read into a storage area and converted to a form suitable for the host code. During the search-interpolate phase, the stored data tables are used to compute the EOS values required by the host code. The set-up routines are called only at problem initialization and hence use little computer time. The search-interpolate routines, however, are called throughout problem execution and hence have been heavily vectorized for the Los Alamos Cray-1 computers. The EOS data available through EOSPAC include thermodynamic properties (e.g., pressure and specific energy) and transport coefficients (e.g., opacity and conductivity).
