9 To create a **Cartesian Grid** in the **Main Menu** select **Model -> Construction -> Make Grid**.
11 Three kinds of grid can be created:
13 - simple cartesian grid (see :ref:`guicartgridsimple`),
14 - uniform cartesian grid (see :ref:`guicartgriduniform`),
15 - custom cartesian grid (see :ref:`guicartgridcustom`).
17 .. _guicartgridsimple:
22 To create a simple cartesian grid, select radio button **Simple**:

28 Dialogue Box for a Simple cartesian grid
31 The following data are required:
33 - *nb X*: The number of hexahedra along the X axis
34 - *nb Y*: The number of hexahedra along the Y axis
35 - *nb Z*: The number of hexahedra along the Z axis
37 The result of this action is:

48 .. _guicartgriduniform:
50 Uniform cartesian grid
51 ======================
53 To create an uniform cartesian grid, select radio button **Uniform**:

59 Dialogue Box for an Uniform cartesian grid
62 The following data are required:
64 - *origin*: The vertex of the origin
65 - *vec X* : The X vector
66 - *vec Y* : The Y vector
67 - *vec Z* : The Z vector
68 - *len X* : The length of an hexahedra on the X axis
69 - *len Y* : The length of an hexahedra on the Y axis
70 - *len Z* : The length of an hexahedra on the Z axis
71 - *nb X* : The number of hexahedra on the X axis
72 - *nb Y* : The number of hexahedra on the Y axis
73 - *nb Z* : The number of hexahedra on the Z axis
75 Clicking on "Apply" on the previous dialog box will produce the following grid (Uniform hexahedra, different sizes on the three axis):

83 TUI command: :ref:`tuicartgriduniform`
85 .. _guicartgridcustom:
90 To create a Custom cartesian grid, select radio button **Custom**:

96 Dialogue Box for a Custom cartesian grid
99 The following data are required:
101 - *origin*: The vertex of the origin
102 - *vec X* : The X vector
103 - *vec Y* : The Y vector
104 - *vec Z* : The Z vector
105 - *X* : A list of x values in ascendant order
106 - *Y* : A list of y values in ascendant order
107 - *Z* : A list of z values in ascendant order
109 A value on each axis gives the length of an hexahedra on that axis from the origin of the grid.
110 For example the first value in the list of x values is the length on X axis of the first hexahedra from the origin.
