GEOMETRY/DRAWING
Create Surface
Simple
structure list
Geometry -> Create -> Object -> Circle -> Enter a center
for the circle -> 0,0
-> Enter a normal for the circle -> Positive Z -> OK -> Enter
a radius for the circle -> 25 -> Enter
Remember that Point = Black color, Line = Blue
color, Surface = Magenta, Volume = Cyan.
Create the Center Quadrilateral Element - To
obtain the better Meshing
Geometry -> Delete -> Surface -> Select the surface (click the magenta
circle) -> Escape
Geometry -> Create -> Line -> Enter points to define line
-> 5,0; 0,5; -5,0; 0,-5 and finally 5,0, successivly
-> Create point procedure -> JOIN -> Escape
Geometry -> Edit -> Divide -> Num Divisions -> Select line to divide
-> If you click the line, the line color change to Red -> Enter Value
Window -> Enter "4" -> You will find 4 points with black color
Geometry -> Create -> Line -> Enter points to define line
-> Click with Thick Cross Cursor successivly -> Create point
procedure -> JOIN -> Escape
Geometry -> Create -> NURBS Surface -> Automatic -> Enter Value Window
-> Enter number "4" -> You will create 5 new surfaces
Create Volumes
Copy
mode
Utilities -> Copy -> Surfaces -> Second
point z=1.0 -> Do Extrude Surfaces -> Select
After selecting the circle (click on the magenta color circle line) -> Finish
When you select the surface (click on the Magenta
line), the surface color Magneta changes to Red!
If Extrude is chosen, the 4 side-surfaces are
also assigned. If you do not choose Extrude, two separate surfaces
are created.
Geometry -> Create -> Volume -> Automatic
6-sided volumes
When you make the volume, you
will find 5 Cyan color volumes.
