摘要：
The complementary volume (co-volume) method is used to discretize the horizontal viscous terms of the Navier-Stokes equation on a triangular unstructured grid. With the co-volume method, the horizontal viscous terms can be discretized without any interpolation. And the co-volume method is less expensive than higher-order interpolation schemes. The co-volume method is implemented within the UnTRIM code. Simulation results of test cases show that the co-volume method is less diffusive than the first-order interpolation scheme used in the original UnTRIM code.
