GASP-V: A Universal Simulation Package

Abstract

An ANSI FORTRAN-IV written subroutine package capable of handling continuous-time problems (described by mixed ODE's and PDE's) as well as discrete and combined problems is presented. GASP-V is fully upwards compatible with GASP-IV, but enlarged by:

  1. some subroutines out of the program FORSIM-V for easy coding of distributed systems (initial value PDE's of parabolic and/or hyperbolic type) using the method of lines.
  2. an effective run-time library for modeling of continuous-time problems comparable to the one offered e.g. by CSMP-III, but coded in a much more effective way, since all discontinous functions are broken up into series of piecewise continuous functions, by utilizing time- and/or state events to switch over from one branch to the other, which leads to a remarkable reduction of execution time.
  3. a comprehensive selection of different integration algorithms placed at the user's disposal.
