An h-p Adaptive Method Using Clouds
Several computational and mathematical features of the h-p cloud method are demonstrated in this paper. We show how h, p and h-p adaptivity can be implemented in the h-p cloud method without traditional grid concepts typical of finite element methods. The mathematical derivation of an a posteriori error estimate for the h-p cloud method is also presented. Severalnumerical examples illustrate th...
متن کاملH-p Clouds-An h-p Meshless Method
A new methodology to build discrete models of boundary-value problems is presented. The h-pcloud method is applicable to arbitrary domains and employs only a scattered set of nodes to build approximate solutions to BVPs. This new method uses radial basis functions of varying size of supports and with polynomialreproducing properties of arbitrary order. The approximating properties of the h-p cl...
متن کاملAn Adaptive Segmentation Method Using Fractal Dimension and Wavelet Transform
In analyzing a signal, especially a non-stationary signal, it is often necessary the desired signal to be segmented into small epochs. Segmentation can be performed by splitting the signal at time instances where signal amplitude or frequency change. In this paper, the signal is initially decomposed into signals with different frequency bands using wavelet transform. Then, fractal dimension of ...

متن کاملH- and P- Adaptive Incompressible Flow Solutions on Cartesian Grids Using Least Squares Spectral Element Method
Use of numerical solutions to flow phenomena has become increasingly common among non-engineering disciplines such as medical sciences. This increasing interest can be promoted by the ability of solvers to obtain accurate numerical solutions without the need for expertise in some specific subjects such as grid generation or automatic grid adaptation. In this work, an incompressible flow solver ...
