Shell [Sym.] (symmetric)
•
The outside surface (1) is the surface geometry of the outer 'parallel' contours with
distance Shell Thickness in mm.
•
The inside surface (1) is the surface geometry of the inner 'parallel' contours with
distance Shell Thickness in mm.
If one of the inside contours is not valid, the inside surface is represented by an inner point
(the inside surface is not visible). (A contour is only valid if the rotation axis is crossed exactly
twice.)
The thickness of the shell can be adjusted by using the left control below the menu area.
To activate the selected shell thickness press the [Activate] key. Then the new shell thickness
is calculated.
The shell contour is accepted and stored. The VOCAL - Static 3D menu
chapter 'VOCAL - Static 3D' on page 9-127 ) appears on the menu
(review:
area.
The shell contour is not accepted and you return to the "VOCAL Modes"
menu, where you can define a new contour.
Of course, only valid reference contours generate a valid shell contour.
The (shell) volume is defined as the difference between the volume defined by the outer
surface (of the shell geometry) and the volume defined by the inner surface (of the shell
geometry). A degenerated surface is symbolized in the display with xxxxx.
The Volume is displayed on the monitor in the lower right quadrant:
Shell xxx.xx cm
Vref. xxx.xx cm
Inside xxx.xx cm
Outside xxx.xx cm
If the reference surface geometry is not valid, all volumes are invalid and displayed with xxxxx.
In this menu several display modes can be selected. You will enter this menu after accepting
the ROI.
Select this key in the "VOCAL - Edit" menu. The defined (shell) contour is accepted, stored
and the result is displayed.
Following menu appears on the menu area.
