SINDA/FLUINT (Ref 1, 2) is a computer program used to analyze thermal/Fluid systems that can be represented in finite difference, finite element, or lumped parameter form. In addition to conduction and radiation heat transfer, the program is capable of modeling steady or unsteady single- and two-phase flow networks, their associated hardware, and their heat transfer processes. Because it is generalized, versatile, and user-extensible, SINDA/FLUINT is a standard in the aerospace industry for modeling thermal control systems. It is also used in the automotive, aircraft, electronics, petrochemical, HVACR (heating, ventilation, air-conditioning, and refrigeration), and process industries. C&R's SinapsPlus™ (Ref 3), a replacement for SINAPS, is a complete graphical user interface to SINDA/FLUINT. SinapsPlus is a schematic-oriented pre- and postprocessor that brings modern visualization methods to a simulation code that lacks geometric constraints.

C8R's SinapsPlus™ is a complete graphical user interface (pre- and postprocessor) and model debugging environment for SINDA/FLUINT (Ref 7, 8). SinapsPlus also supports the C and C++ languages in addition to the traditional choice of Fortran for concurrently executed user logic.

Over the past 15 years, the industry standard tool for thermal analysis, SINDA, has been expanded to include advanced thermodynamic and hydrodynamic solutions (“FLUINT”). With the recent culmination of the unique modeling tools that are described in this paper, and with concurrent expansions described elsewhere (Ref 1), SINDA/FLUINT has arguably become the most complete general-purpose thermohydraulic network analyzer that is available. These advances have enhanced the usage of the code in the areas of liquid propulsion, fire suppression, and environmental control systems (ECLSS), providing for the first time a common framework for analysis and data exchange between engineers in these otherwise distinct specialties.
