In the preprocessing part of GiD there are two basic modes the user can work with: geometry and mesh. Just in order to see how the mode can be changed we are going to generate a mesh with all the default parameters and general edge size=1.0.
- Select Mesh->Generate mesh... The following window should appear.
- Click OK and wait for the mesh generation. Once the mesh is generated, a window pops up and shows the user the result from the mesh generation.
- Click on 'View mesh' option, and the following visualization of the model should appear:
The color of the mesh in render normal could be set in Preferences Graphical - Colours,
e.g. can set the elements color to gray or other color.
Now we are in 'mesh' mode. Changing the render mode user can see that the color of the mesh entities also follows the Layer colors.
Selecting View->Mode->Geometry user can change to the geometry mode again. The 
icon in the toolbar switch between both modes
