$triranges

$triranges reading in the geometric parameters. $triregionnumber, and $triregiontype should be defined before the $triranges

$triranges
@f1 @f2 @f3 @f4 @f5 @f6
@f1 @f2 @f3 @f4 @f5 @f6

@f1 @f2 @f3 @f4 @f5 @f6 are defined below according to its type.

Example of @type

@type.1~4 are triangle, circle, ellipse and rectangle.

@type = 1 is triangle. If it have n-trianges, it it repeating along x direction.
@type = 11 is triangle. If it have n-trianges, it it repeating along y direction.
@type = 2 is circle. If it have n-circles, it it repeating along x direction.
@type = 21 is circle. If it have n-circles, it it repeating along y direction.
@type = 3 is ellipse. If it have n-ellipses, it it repeating along x direction.
@type = 31 is ellipse. If it have n-ellipses, it it repeating along y direction.
@type = 4 is rectangle. If it have n-rectangle, it it repeating along x direction.
@type = 41 is rectangle. If it have n-rectangle, it it repeating along y direction.

If the parameters are not show in the figure, you should set those parameters as 0.

Type5~8 are sine shape period structure.

Type.5 and 6 can be determined by this expression:

$f_6<y<f_1sinf_2x+f_3;$

$f_4<x<f_5$

Type.7 and 8 can be determined by this expression:

$f_6<x<f_1sinf_2y+f_3;$

$f_4<y<f_5$

Example

For example:

$triregionnumber
3

$triregiontype
1  1 0.0
2  2 20.0
41 3 2.0 

$triranges
4.0  4.0  8.0  4.0  6.0  8.0 
10.0 12.0 2.0  0.0  0.0  0.0
13.0 4.0 14.0  5.0  0.0  0.0
