An Overview of the SAFSIM Computer Program

SAFSIM (System Analysis Flow SIMulator) is a FORTRAN computer program that provides engineering simulations of user‐specified flow networks at the system level. It includes fluid mechanics, heat transfer, and reactor dynamics capabilities. SAFSIM provides sufficient versatility to allow the simulation of almost any flow system, from a backyard sprinkler system to a clustered nuclear reactor propulsion system. In addition to versatility, speed and robustness are primary goals of SAFSIM development. The current capabilities of SAFSIM are summarized and some sample applications are presented.
