This method is appropriate to employ under structured and unstructured meshes. Mixed grids, combining both types of grids, are investigated. The coupling of different grids is done by overlapping strategy. The computational effort for the mixed grid is evaluated by the CPU-time, with different percentage of covering area of the unstructured mesh. The present scheme is tested for the driven cavity problem, where the incompressible fluid is integrated by calculating the velocity fields and computing the pressure field in each time step. Several schemes for unstructured grid are examined, and the compatibility condition is applied to check their consistency. A scheme to verify the compatibility condition for the unstructured grids is presented. %8 Nov. %N 1/4 %T Criteria for mixed grids in computational fluid dynamics %@secondarytype PRE PI %K Computational fluid dynamics, Mixed grids, Finite volume method, Incompressible fluid, Compatibility condition. %@group %@group LAC-INPE-MCT-BR %@group LAC-INPE-MCT-BR %@secondarykey INPE-14377-PRE/9464 %@copyholder SID/SCD %@issn 0378-4754 %2 sid.inpe.br/mtc-m17@80/2006/11.30.17.37.28 %@affiliation Unesp %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %B Mathematics and Computers in Simulation %P 156-167 %4 sid.inpe.br/mtc-m17@80/2006/11.30.17.37 %D 2006 %V 73 %A Doescher, Ervwin, %A Campos Velho, Haroldo Fraga de, %A Ramos, Fernando Manuel, %@dissemination PORTALCAPES %@area COMP
