Abstract (2. Language): 
The first step in numerical analysis techniques is the preparation of a suitable mesh for solution domain. In the finite element method, the mesh generation, as a preprosessing stage, affects the accuracy of the results importantly. Furthermore, it is very time consuming when it is not carried out automatically. In this study, an automatic mesh generation technique which can be used for plane and axisymmetric problems is introduced. Meshes prepared with this technique for several geometries are given. With the computer program developed for this study, the desired domains can be divided into 3 node triangular and 4, 8 and 9 node quadrilateral elements with least input information and suitably fine meshes.

Abstract (Original Language): 
Nümerik analiz yöntemlerinin birinci adımı genellikle çözüm bölgesinin elemanlara ayrılarak bir ağ yapısının elde edilmesidir. Sonlu elemanlar metodunda da ön işlemlerden olarak sonlu eleman ağının elde edilmesi sonuçların güvenilirliği açısından büyük öneme sahiptir ve otomatik olarak yapılmazsa çok zaman alıcı bir aşamadır. Bu çalışmada, düzlem ve eksenel simetrik problemlerin çözümünde kullanılabilecek bir otomatik ağ oluşturma yöntemi tanıtılarak ele alınan çeşitli geometrilerin sonlu eleman ağları verilmiştir. Hazırlanan bilgisayar programı istenen bölgeyi istenen sıklıkta ve en az girdi bilgisiyle 3 düğümlü üçgen ve 4, 8 ve 9 düğümlü dörtgen elemanlara ayırmaktadır.
