Creating a surface inside a Volume

[Mik]

Dear Community,

I would like to know if we can create a surface inside a volume to impose some conditions on it such as an adiabatic one. ![Capture|690x294]
I have attached an image to illustrate. So for the 1st iteration, I would like to have “1” as my adiabatic surface (the dotted one) and for iteration “2” the next part; so on and so forth.

Thanks in advance for your help.

Sincerely

You can build 3d mesh with internal boundary, but to add adiabatic condition (du/dn)=0
on this internal surface is not so easy, I have no simple idea to that.

Thank you with the internal boundary everything is working well.
