Plotting Random Geometry on Comsol Live link with Matlab.

I am working on Comsol Live Link for Matlab. I am trying to plot random circles in a certain range without overlapping. I am able to plot the circles however the circles will overlap and I can't find a solution for that. Please see the code below.

clc
  model = ModelUtil.create('Model2');

geom1 = model.geom.create('geom1', 2);

r=1;C1=2;C2=2;C3=1; %matlab variables
model.param.set('r',r,'radius');
model.param.set('C1',C1,'coordinate of center');
model.param.set('C2',C2,'coordinate of center');
%model.param.set('C3',C3,'coordinate of center');
prompt= 'Enter the value N \n';
N=10; %input(prompt);%This may vary based on user input
for j=1:1:N
tag=model.geom('geom1').feature().uniquetag('sph');
model.geom('geom1').feature().create(tag,'Circle');
model.geom('geom1').feature(tag).set('r', r);
model.geom('geom1').run(tag);
r=r+(5-r).*rand(1,1)
end
for j=1:1:N
model.geom('geom1').feature(tag).set('pos', [C1 C2]);
C1=C1+(5-C1).*rand(1,1)+r
C2=(C2+(5-C1).*rand(1,1))+r
model.geom('geom1').run(tag);
end

model.label('Model2.mph');
mphgeom(model)

Hi Iqbal,

I'm curious if you ever found a solution to this? I am currently searching through forums on how to do this exact process.

Dear Mr. Iqbal

I am also usinh Matlab to generate geometry for COMSOL. However, when I export the mph file, it is empty. That means the code I downloaded from inter it is not linked to the model. Could you let me know how you linked your code to model?

Thank you very much.
