ERROR ESTIMATION AND MESH OPTIMIZATION FOR CLASSICAL FINITE ELEMENTS

ERROR ESTIMATION AND MESH OPTIMIZATION FOR CLASSICAL FINITE ELEMENTS We present several applications for 2D or axisymmetric elasticity problems of a method to control the quality of a finite element computation, and to optimize the choice of meshes. The method used, which is very general, is based i on the concept of error in constitutive relation and ii on explicit techniques to construct admissible fields. Illustrative examples are shown for several 2D or axisymmetric elements 3 or 6 node triangles, 4 or 8 node quadrilaterals. They have been achieved with our code ESTEREF, a postprocessor of error computation and mesh optimization which can be interfaced with any finite element code. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Engineering Computations: International Journal for Computer-Aided Engineering and Software Emerald Publishing

Abstract

We present several applications for 2D or axisymmetric elasticity problems of a method to control the quality of a finite element computation, and to optimize the choice of meshes. The method used, which is very general, is based i on the concept of error in constitutive relation and ii on explicit techniques to construct admissible fields. Illustrative examples are shown for several 2D or axisymmetric elements 3 or 6 node triangles, 4 or 8 node quadrilaterals. They have been achieved with our code ESTEREF, a postprocessor of error computation and mesh optimization which can be interfaced with any finite element code.
