ANSYS software is equipped only with a 2-D triangular singular element, but neither with 2-D rectangular nor with 3-D singular elements. Around the node at the crack tip, a circular area is created and is created and is divided into a designated number of triangular singular elements.
Since you are discretely defining a continuous domain, the degree to which the salient features of the flow (such as shear layers, separated regions, shock waves, boundary layers, and mixing zones) are resolved , depends on the density and distribution of nodes in the mesh.In many cases, poor resolution in critical regions can dramatically alter the flow characteristics.In a previous blog entry, we introduced meshing considerations for linear static problems.One of the key concepts there was the idea of mesh convergence — as you refine the mesh, the solution will become more accurate. In this post, we will delve deeper into how to choose an appropriate mesh to start your mesh convergence studies for linear static finite element problems.Fortunately there is a Matrix Market format sponsored by NIST that is also supported by Ansys and Matlab. There are two very useful MATLAB functions created just for this purpose: mmread.m for reading in the Market Matrix file into MATLABmmwrite.m for writing the matrix into a Matrix Market file
