Hey!
I want to place multiple spheres (100 - 400) in a cube. I have an array of co-ordinates ( x, y, z) defining the center of sphere and a vector of all the radius ( r) of spheres. Is there anyway by which i can make such a model in Comsol geometry?

I think you can do it using Matlab code, but I do not know how. Maybe you can try contacting the person who started this thread: www.comsol.co.in/community/forums/general/thread/46371/.

% Create geometry in 3D
geom1 = model.geom.create('geom1', 3);

% Create spheres
for i = 1:N
name = strcat('sph',int2str(i));
model.geom('geom1').feature.create(name, 'Sphere');
model.geom('geom1').feature(name).set('r' , r(i) );
model.geom('geom1').feature(name).set('pos', [X(i) Y(i) Z(i)]);
end
% Create geometry in 3D geom1 = model.geom.create('geom1', 3); % Create spheres for i = 1:N name = strcat('sph',int2str(i)); model.geom('geom1').feature.create(name, 'Sphere'); model.geom('geom1').feature(name).set('r' , r(i) ); model.geom('geom1').feature(name).set('pos', [X(i) Y(i) Z(i)]); end
