Accuracy, Adaptive Methods and Complex Geometry

چکیده
We describe our approach to computing accurate solutions for time dependent fluid flows in complex geometry. We use regular, embedded, Cartesian grids wherever possible. We describe our adaptive mesh refinement algorithm and our strategy for treating geometric complexity using non-body-fitted Cartesian grids. The trade-offs of block-structured vs. unstructured data structures are presented. Several open problems are discussed that need to be resolved both to automate and improve the accuracy of computations.

Objectives: Automated Auditory Brainstem Responses (ABR) peak detection is a novel technique to facilitate the measurement of neural synchrony along the auditory pathway through the brainstem. Analyzing the location of the peaks in these signals and the time interval between them may be utilized either for analyzing the hearing process or detecting peripheral and central lesions in the human he...
متن کاملEffects of Directional Subdividing on adaptive Grid-Embedding (RESEARCH NOTE)
The effects of using both directions and directional subdividing on adaptive gridembedding on the computational time and the number of grid points required for the same accuracy are considered. Directional subdividing is used from the beginning of the adaptation procedure without any restriction. To avoid the complication of unstructured grid, the semi-structured grid was used. It is used to so...

متن کاملCombination of Adaptive-Grid Embedding and Redistribution Methods on Semi Structured Grids for two-dimensional invisid flows
Among the adaptive-grid methods, redistribution and embedding techniques have been the focus of more attention by researchers. Simultaneous or combined adaptive techniques have also been used. This paper describes a combination of adaptive-grid embedding and redistribution methods on semi-structured grids for two-dimensional invisid flows. Since the grid is semi-structured, it is possible to us...
