A new subroutine monitors the liquid and gaseous fuel phases and energy balance data and emissions are monitored and printed. Extensions to the particle-based liquid wall film model made the model more complete and a split injection option was also added. A new option provided automatic deactivation of a port region when it is closed from the cylinder and reactivation when it communicates with the cylinder.

New features enhanced the robustness, efficiency, and usefulness of the overall program for engine modeling. including video editing, 3d animation, matte painting, 2d illustration and web design. KIVA-3V also contains a number of significant improvements over its predecessors. Cell-face boundary conditions permit greater flexibility and simplification in the application of boundary conditions.
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. KIVA-3V uses a block-structured mesh with connectivity defined through indirect addressing. KIVA3, in turn, was based on the earlier KIVA2 (1989) and used the same numerical solution procedure and solved the same types of equations. IVA-3V is the most mature version of KIVA still maintained and distributed through LANL it is an improved version of the earlier Federal Laboratory Consortium Excellence in Technology Transfer Award-winning KIVA3 (1993), extended to model vertical or canted valves in the cylinder head of a gasoline or diesel engine.
