Hi everyone,

I am trying to create a 3D voronoi diagram for COMSOL using MATLAB livelink for COMSOL.

I am using this file from this link https://www.mathworks.com/matlabcentral/fileexchange/50772-polytope-bounded-voronoi-diagram-in-2d-and-3d

When I createda geometry in Matlab Livelink Comsol by follow step:

Step 1: On Comsol server I type model=ModelUtil.model('Model');

Step 2: On Matlab command:

model=ModelUtil.model('Model');

geom1=model.geom.create('geom1',3);

Step 3: I copy the code from demo file of the link above and paste on Matlab command.

Step 4: I enter and the software plot an image as I expected.

However, when I save the model as an mph file, and open it in COMSOL, there is nothing. I also type mphgeom(model) to open the model but it's empty.

That means the voronoi diagram is not included in the geometry.

My question is how can I add the voronoi diagram which create by another guy into geom1?

If you have any experience on this problem, please let me know. Thank you very much.
