Modifications and Improvements to the BRLHELP Code

Abstract

Input to the BRLHELP code has been changed to NAMELIST format. A previous fatal condition, overemptying of pure cells, has been converted to a non-fatal condition. Pressure iteration failure for mixed cells has been eliminated by employment of a mass-weighted average pressure scheme. A call to the BRLEOS code has been installed in the old EQST subroutine to allow access to a variety of equations of state including BRLGRAY which provides temperature as an output variable. A problem with the FORTRAN compiler on the BRL Cyber 176 is circumvented. UPDATE modifications are listed, code input is discussed, and a sample calculation is given.
