This course is focused in the basic meshing features and capabilities of GiD.
To follow this course, the models gid_model_basic_meshing_course.gid and gid_embedded_example.gid must be loaded from the folder where the courses material is.

...

• Select Mesh->Semi-structured->Volumes->Assign number of divisions to volume lines 

and set as 4 the number of divisions to be assigned.

• Then select volumes number 1 and 4 and press ESCAPE to leave the selection mode.
• Generate the mesh. The result should be as the one shown in the following figure:

...

• Select Mesh->Semi-structured->Volumes->Set ->Structured structured direction. Then select line 25 (the line labeled in the next figure).

For this section, we will work with the model gid_embedded_example.gid (it can be loaded from the folder where the courses material is). This model have a cubic volume, and the skin surface of a sphere.

As explained before, an embedded model consists in some volumes (the calculation volumes), and embedded regions defined by collection of surfaces. In this case, the calculation volume is the cube, and the embedded region is defined with the sphere surfaces.

First of all, select the 'Embedded' mesh type in the Meshing→general branch of the preferences window.

Then, generate the mesh of the model (Mesh→generate), using a general mesh size of 1. The following mesh should be generated:

View of the mesh generated.

As an embedded mesh, it can be seen that the volume mesh is fitted to the calculation volume (cube), and it is not conformal nor body-fitted to the embedded region (sphere skin).

A field of signed distances to the embedded contours has been calculated on the nodes of the calculation volume mesh. They are stored with the model, and can be appreciated going to the post-processing part of GiD (where they are loaded as a result), and visualizing the contour fill of it, or some iso-surface (for instance).
