Mesh grading in isogeometric analysis
This paper is concerned with the construction of graded meshes for approximating so-called singular solutions of elliptic boundary value problems by means of multipatch discontinuous Galerkin Isogeometric Analysis schemes. Such solutions appear, for instance, in domains with re-entrant corners on the boundary of the computational domain, in problems with changing boundary conditions, in interfa...
متن کاملIsogeometric analysis : CAD , finite elements , NURBS , exact geometry and mesh refinement
The concept of isogeometric analysis is proposed. Basis functions generated from NURBS (Non-Uniform Rational B-Splines) are employed to construct an exact geometric model. For purposes of analysis, the basis is refined and/or its order elevated without changing the geometry or its parameterization. Analogues of finite element hand p-refinement schemes are presented and a new, more efficient, hi...
متن کاملResults-based mesh refinement with ANSA / μETA pre- and post- processing suite
Ideally, a mesh should represent the initial shape of a structure in such precision that will ensure the accuracy of the results. Furthermore, especially for small features, where stresses are higher, the description should be even more accurate. Generating, however, a fine mesh globally would add up to computational costs. In addition, it is not always obvious which areas should be manually re...
متن کاملThe role of Bézier extraction in adaptive isogeometric analysis: Local refinement and hierarchical refinement
We present 2 adaptive refinement techniques, namely, adaptive local refinement and adaptive hierarchical refinement, for isogeometric analysis. An element-wise point of view is adopted, exploiting Bézier extraction, which facilitates the implementation of adaptive refinement in isogeometric analysis. Locally refined and hierarchical T-splines are used for the description of the geometry as well...
متن کاملAnalysis of Pre-processing and Post-processing Methods and Using Data Mining to Diagnose Heart Diseases
Today, a great deal of data is generated in the medical field. Acquiring useful knowledge from this raw data requires data processing and detection of meaningful patterns and this objective can be achieved through data mining. Using data mining to diagnose and prognose heart diseases has become one of the areas of interest for researchers in recent years. In this study, the literature on the ap...
