KIVA3 is a computer program for the numerical calculation of transient, two and three-dimensional, chemically reactive flows with sprays. It is an extension of the earlier KIVA2, and uses the same numerical solution procedure and solves the same set of equations. KIVA3 differs in that it uses a block-structured mesh with connectivity defined through indirect addressing. The departure from a single rectangular structure in logical space allows complex geometries to be modeled with significantly greater efficiency because large regions of deactivated cells are no longer necessary. Cell-face boundary conditions permit greater flexibility and simplification in the application of boundary conditions.

• Resource Relation: Other Information: DN: Source code requires UPDATE to generate a compile file. Linear system solver, such as in LINPACK, is required for equilibrium chemistry solver. Several calls are made to run-time libraries. Graphics postprocessor requires primitives for point plotting and vector drawing, along with character string conversion for plot labels. Source was compiled on a CRAY Y-MP8/864.; PBD: 1 Mar 1993
