Mesh Generation

As usual we will generate a 2D mesh by means of GiD's meshing facilities. We will use a mesh composed of tetrahedral inside the circle and quadrilaterals for the rest of the domain. In order to do it, we have to use the option Meshing>Element type>Quadrilateral and select the external surface 2 of Figure 113).

To generate the mesh, the global is chosen of 0.025, at an Unstructured size transition of 0.5.

With these parameters a mesh is generated, consisting of about 16000 nodes and 750 triangle elements and 16000 quadrilateral elements (see Figure 92).
