Abstract: The main aim of this paper is to have an accurate analysis on the famous Adini’s element for the second order problems under to the anisotropic meshes.We firstly show that the interpolation of Adini’s element satisfy the anisotropic property.Then the optimal error estimate is obtained without the regularity assumption on the meshes.


Key words: Adini's element, anisotropic, regularity assumption, error estimate
