Creating an entire cylinder

    The method is similar to the one for the semicylinder.

    DDN for the geometry:

1- Change of design and visual parameters

    Design and visual parameters must be changed with the same values as the semicylinder.

2-Points creation

    Like for the semicylinder, create two points corresponding to the two centers of the circles.

3- Cylinder creation

    Proceed in the same way than the semicylinder with an ending angle of 360.   .

4- Cylinder conversion

    The cylinder must be converted in B-spline surface by  and . Then select the cylinder and validate with the mouse. Choose 1-entire surface and enter 16 (enter) for 1-U order and 2-V order. Validate with the mouse.

    Come back to the main menu and close all menus opened.
 
 
 

5-Isoparametric curves creation

    Select  and the bottom right icon of the  . Select the cylinder with the mouse and choose 3-Four edges .

    Come back to the main menu and close menus opened.
 

6-Removal of a curve

    Put the longitudinal curve in yellow to the dustbin by blanking the cylinder in a first time, clicking on  and selecting the curve in a second time : we don't need of this curve .

    Come back to the main menu and close menus opened.
 

7-Segmentation of circle curves:

    The two circle curves must be segmented into 4 parts. So click on . Select one of the two circle curves with the mouse and choose 4-Divide into N segments, enter 4 for the number of segments and at last choose 2-Delete.
    Redo the same thing for the other circle curve.

    Come back to the main menu and close menus opened.
 

8- Surfaces creation

    Create the two circle surfaces of the cylinder as it has been done for semicylinder (
section 5 and 7).

9- Interior point creation

    Create a interior point (see section 8 of the semicylinder).

    The geometry is now terminated.
 

   10-Save the geometry



 

    DDN->tetin  for the families:

    It is the same method here than for the semicylinder. Create 4 families : inlet, outlet, wall and fluid.  Create also the material domain, save and quit.






    Proceed to the tetrahedra meshing as for the semicylinder.


    Save the file which will be readen by Fluent5 with "Output" (see end of section about semicylinder).
