I've managed to compile a script that generates me some nodes that are
distributed in the way I described, however with a slight random
distortion of the coordinates:
dx = 500 ;
dy = 250 ;
n = 0 ;
m = 0 ;
k = 0 ;
randx = 0 ;
randy = 0 ;
x = 0 ;
y = 0 ;
xmax = 1000 ;
ymax = 500 ;
distort = 3 ;
For x In {0:xmax/dx}
For y In {0:ymax/dy}
n=n+1;
randx=0;
randy=0;
If(x!=0 && x!=xmax/dx)
randx=Rand(dx/distort);
EndIf
If(y!=0 && y!=ymax/dy)
randy=Rand(dy/distort);
EndIf
Point(n)={x*dx+randx,y*dy+randy,0,dx};
m=n-1;
If(m>0 && y!=0)
k=k+1;
Line(k)={n,m}; //nach unten
EndIf
m=n-ymax/dy-1;
If(m>0 && x!=0)
k=k+1;
Line(k)={n,m}; //nach links
EndIf
EndFor
EndFor
I can't however create a plane surface from these lines and points
with my internal points and lines being taken into consideration. Can
you help me with this?
Zitat von "Ruth V. Sabariego" <[email protected]>:
Try this:
a = 100 ;
lc1 = 10 ;
lc2 = 1 ;
Point(1) = {0,0,0,lc1};
Point(2) = {a,0,0,lc1};
Line(1) = {1,2};
Extrude {0, a, 0} {
Line{1}; Layers{a/lc2};
}
Regards,
Ruth

Hi,
I'm pretty new to gmsh, and so far I haven't succeeded in creating
a mesh with different element sizes in different spatial directions
(for instance a 100m*100m square with average element sizes of 10m
in x direction and 1m in y direction).
Is this possible, and if so, can you show me how to do that (either
script or GUI)?
Thanks in advance for your thoughts,
Martin
