You can use the interval block to define your domain (like in 2d) but that has nothing to do with the<br>
boundary ids. Have a look at the boundarydomain block which should do exactly what you need<br>
(it also uses an "interval" to define a region with the same boundary id).<br>

<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hi everybody,<br>
<br>
I would like to ask you a question about how to prescribe boundary IDs within a DGF file.<br>
I just had a closer look at the DGF format, but I couldn't find how to do what I need.<br>
<br>
Let's say that the domain for your computations is a cube (or a rectangular cuboid, it doesn't matter), and you want to impose different boundary conditions on the six faces.<br>
In order to do that, I would introduce different boundary IDs to be read in the code, to guarantee that the faces are treated accordingly.<br>
<br>
If you want to assign the same ID to all the faces of elements lying on a certain big face of the cube, is it possible to do it directly, without enumerating all those faces?<br>
I mean, in 2D there is the excellent command "Interval".<br>
What happens if I use the keyword "Interval" (in 3D), passing the four segments forming the perimeter of the (big) face?<br>
<br>
Thanks in advance! <br>
