Such a configuration has proved the grid elements of ventilation modules exert a higher influence on the results than the positioning of modules on the façade.
The use of an adequately refined mesh around the airfoil, that is formed by triangles placed in a quasi-structured way, allows for the generation of grid elements of moderate aspect ratios.
For the content analysis, the repertory grid elements of each teacher's group were pooled and categorized according to the meanings they expressed.
Due to the limitation of space, the detailed explanation of the Richardson extrapolation, the AMR tolerance, and other components of the AMR algorithm, such as tagging and buffering of coarse grid elements, implementation of the V-cycle multigrid iteration on the adaptively refined grids, and the data up-/downscaling between coarse and fine grids, are all omitted.
where S j is the sensitivity of grid element j of size Δ j, f i (m) is the forward solution of model m, m j is the resistivity change of grid element j, σ i is the standard deviation of the data, and N is the number of elements = number of observation sites × number of frequencies × data types.
We develop a finite-element electro-optical simulation for OLED using grid structures to optimize geometry, thickness and width of grid elements.
Adaptive quadtree grids are able to focus on regions of interest such as pollutant fronts, while retaining economy in the total number of grid elements through selective grid refinement.
The accuracy of numerical results was evaluated in terms of the physical approximation errors, namely inlet boundary conditions and turbulence models, and spatial discretization errors due to the number of grid elements and grid refinement near solid surfaces.
The number of grid elements equal to 844740 was chosen in further calculations to ensure reasonably fast and accurate computations, the independence of grid used, and repeatability of the results.
Each field was subdivided into an epithelial and a stromal compartment, and for both compartments, cellular infiltration (n i ) and the compartment's area (number of grid elements, a i ) were recorded separately.
The side length of the grid elements constituting the square region was recommended as 0.5 m and the number of spray directions was 180 in the simulation.
