Hello Yuri,
You could achieve such a geometry either with MATLAB (assuming you have LiveLink for MATLAB) or with a method in an application (assuming you use COMSOL on a Windows computer so you have the Application Builder).
Best regards,
Jeff

Jeff, thanks, Can I, once built it in app builder bring it back to COMSOL

Yes, an app can be used to create an "incomplete" mph file, e.g. one that contains just a geometry. You can then open that mph file in the GUI and continue from there.

The topic of generating a geometry with the Application Builder seems to pop up more and more often in the Discussion Forum, so I am attaching a simple example.
The app consists essentially in just one method. That method is triggered by one button. The method is written to create 7 equally spaced blocks of increasing sizes.
There is a Save menu that lets you save the mph file under a new name.
You can then open that mph file in a fresh GUI and add physics, mesh, etc. Alternatively, you can use "Insert Sequence" in an existing model file to import the 7 blocks. See PS below.
Using this approach, you can quickly generate geometries that would be tedious to put together in the GUI. You can also use this approach to generate randomized geometries - something that cannot be done in the GUI.
I hope this helps.
Best,
Jeff
PS: Yet another alternative is to, in the app, export the geometry as a .mphbin file instead of saving it in a .mph file. You then Import the .mphbin file into a new mph file. This has the benefit of not populating your new mph file's Geometry branch with lots of nodes you don't need.

Hi Jeff,
But if we have never used JAVA scripts before? How could we use the application builder as mentioned ?
Thanks

I'll speak from personal experience: I learned a bit of Java way back in grad school and had forgotten most of it by the time COMSOL came up with apps. What I've found is that the Application Builder includes several tools that make it easier to develop methods if you do not have prior experience with Java (or limited experience like myself): "Record code", "Language Elements", "Model Expressions", as well as code completion and a built-in debugger.
There have been a few webinars that discuss some of these capabilities. You can find archived webinars on the App Builder here:

Okay thank you ! I hope that i could understand it because i need it to build my geometry !
Kind regards Jeff
