Create grids

To create a Grid in the Main Menu select Model -> Make grid

Three kinds of grid can be created:

• cartesian grid (see Cartesian grid)
• cylindrical grid (see Cylindrical grid)
• spherical grid (see Spherical grid)

Cartesian grid

To create a cartesian grid, the following data are required:

• the vertex of the initial hexahedron
• the vector corrsponding to the diametrically opposite vertex to the initial vertex
• the number of repetition of this hexahedra along the three axes (n(x), n(y) and n(z))

The dialogue box for the creation of a cartesian grid is:

Dialogue Box for a Cartesian grid

The result of this action is:

todo a revoir:

Result Cartesian Grid

TUI command: Make cartesian grids

Cylindrical grid

To create a cylindrical grid, the following data are required:

• the coordinates (vertex) of the cylinder base center
• the vectors defining the axe and the direction of the cylinder
• the radial, angular and axial sizes: dr, da, dl
• the radial, angular and axial elements number: nr, na, nl
• choose to fill or not the central part of the hexahedra

Spherical grid

To create a spherical grid, the following data are required:

• the vertex of the central hexahedron
• the vector corrsponding to the diametrically opposite vertex to the initial vertex
• the number of embedded hexahedra (nb)
• todo k ??????
