Good day. Please tell me how to draw a ring in 2D in a side projection so that the program perceives it as a whole element? Because when drawing it from the side, the ring looks like a rectangle torn in the middle. This is necessary for constructing a Langevin piezoelectric emitter in 2D. Even if these two pieces are combined in geometry, then when choosing a material, it still breaks it into two pieces.

Hello Sergey,
If this system is axisymmetric, then you should select 2D axisymmetric in the Model Builder. Then you will see that in the Graphics window when you are drawing the geometry the axis of revolution r=0 is shown; you should draw (half of what you currently have in your screenshots) on the r>=0 half.
For an example, see this tutorial or many others in the Application Gallery. Best,
Jeff

Thank you very much.

If the system as a whole is not axisymmetric (another Langevin appears, located nearby, and the elements above them are not axisymmetric), then what to do? It is also possible to draw this in 3D, but the calculation will be very, very long, if it is calculated at all.

A 2D axisymmetric analysis can only be performed if the phenomenon is indeed axisymmetric. You may need to (try to) go 3D.

Got it. Thank you.

- Use correct punctuation. Avoid run-on sentences.
- Try to avoid using “text speak”, “net speak”, or slang. The purpose of language is to be understood.
- Never invent acronyms and use as few acronyms as possible. For example, write "COMSOL Multiphysics" and not "CMP".
- Review your post before publishing it. Try to catch typos.
- Please check to see if a topic has already been posted. Do not post multiple threads on the same topic.
