Creating geometry features with LiveLink for Matlab

I do it in a simple "for"-loop, but the program slows down with an increasing number of circles.
Is there a more efficient way?
Thanks!

Isnt there a copy array feature in the matla calls, as in the GUI ?
probably it's quicker inside the COMSOL geometrical soler than via a matlb COMSOL link per cercle.
Anyhow, are ther no other way to avoid so many features/entities by some clever symmetry use?
As, your model will become really slow and heavy to handle.
We have some models with 800-900 entities in 3D, but made within the GUI, you need a minute or two to move up and down, and one should turn OFF the default replotting option in the preferences

I am trying to do the same thing but with rectangles. how did you do It in 4.2? I was able to make a geometry array of rectangles in 3.5a but I am trying to do it in 4.2 and I am having trouble since it keeps telling me that a variable with that name already exists.
Error in TEDgeom (line 43)
G{i} = geom2.feature.create('r1{i}','Rectangle');
An object with the given name already exists
- Name: r1{i}
did you find a way to create the geometry objects without giving them each a unique name?
Thanks for any advice.

your variable name is probably "i" that is by default sqrt(-1) the complex "i" try using another name and try to avoid to short (1 lettre names)

I have the same question:
I need to create an array of geometry features, like blocks.
I use a simple for loop but it shows an error:
That's the syntax I am using:
for a=1:1:100
b1{a} = geom1.feature.create ('b1{a}', 'Block');
end
Would you mind telling me the correct syntax to create and array of geometry features?
Many Thanks
