Before presenting all the possibilities that GiD offers, we will present a simple example that will introduce and familiarize the user with the GiD program.
The example will develop a finite element problem in one of its principal phases, the preprocess, and will include the consequent data and parameter description of the problem. This example introduces creation, manipulation and meshing of the geometrical entities used in GiD.
First, we will create a line and the mesh corresponding to the line. Next, we will save the project and it will be described in the GiD data baseform. Starting from this line, we will create a square surface, which will be meshed to obtain a surface mesh. Finally, we will use this surface to create a cubic volume, from which a volume mesh can then be generated.
