Generation zone i
Ver: 0
 

DESCRIPTION

This menu allows to set the parameters of a generation zone in a mixing task. A generation zone can be of different types and have a specific generation intensity with respect to others zones.   OPTIONS
 
 -1 
 Upper level menu
1
 Enter the name of this generation zone
Allows to specify the name of the current generation zone
2
 This zone is all the flow domain
The zone is the flow domain itself. Points will be randomly generated throughout the whole flow.
3 This zone is a box included in the flow domain
The zone is a box defined by its two corners (xmin,ymin,zmin) and (xmax,ymax,zmax).
There can be only one zone of this type in a mixing problem !
4 This zone is all the inflows of  the flow domain
In another mixing menu, the user must specify the boundaries that are the inflows of the problem.
This option asks for a random generation of points at all those inflows.
5 This zone is defined by topological operations
Allows for using topological operations for the definition of the generation zone.
6 Enter the intensity of the generation of points
Allows to specify the intensity, the frequency, of point generation in comparison with other generation zones.
  NOTES
 
The parts of a finite elements mesh are numbered as follows :
Topological part Local id Global id
   root mesh     R     1
   subdomain 1 to nbdom     S1 to Snbdom     2 to nbdom +1 
   boundary 1 to nbbnd    B1 to Bnbbnd    nbdom + 2  to  nbdom + nbbnd + 1
Remark : the root mesh has the local id "R", and the global id "1", but in order to avoid problems, don't make any reference to it !
If you want to generate points at the union of two parts i and j, you define the zone like this : (i+j).
If you want to generate points at the intersection of two parts i and j, you define the zone like this : (i*j).
If you want to generate points at the boundary of the part i, you define the zone like this : $(i).
Of course, you can combine these three kind of topological operations.

Example : $(i+j) means "boundary of the union of the parts i and j".

You can use the local identificator or the global one, but don't forget the letter S (or B) before the index of the sub-domain (or the boundary) if you use the local identificators.
