How to create a geometry in Matlab livelink Comsol using downloaded code?

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.

Have you solved the problem?I am in the same trouble as you.Can you give me some guidance?

It is because you didn't link the code to your geometry.

After running the file exchange, you will receive something. In my case I receive the coordinate of points. Then from that coordinate I can use livelink Matlab for COMSOL to generate my geometry.

Hi Trung,I'm having the same problem, can you give some more specific guidance? Thank you very much!!
