How is it possible to show volume plot for a special section of a 3D domain?
My 3D whole domain starts from x= [90-700(m)]
y=[50-500(m)]
z=[-10-2(m)]
But I want to show volume which is x=[360-400(m)]
y=[100-450(m)]
z=[0-2(m)]
I attached my domain and the parts that I want to plot in picture here (for better explanation).
How is it possible to plot it in comsol? Is it possible?
Thanks in advance for help

Another option is to add a Filter subnode to the Volume plot, and in its Logical expression for inclusion field use a logical expression for the spatial coordinates to plot only the fraction of the volume that fulfills that expression.

Could you kindly explain which selection type should I consider and how? Do you have any example?
Looking foreard to hearing from you.

Have you tried creating a Selection and applying it to the data set with your solution?

Great, I solved my problem with your solution. But let me ask, I confronted with 2 questions:
1)When I tried to write logical expression like this: x > 360 && x < 400 && y > 100 && y < 450&& z > 0 && z < 2, then I was not able to show the volume plot, then I removed the z part, and it worked but
2)I applied this logical expression: x > 360 && x < 400 && y > 100 && y < 450
and I got plot (attached picture). I was expecting to have rectangle block but i is irregular block!
Is it related to my geometry? How is it possible to have simple rectangular block from this domain?
Hope to hear from you.

Hi,

In COMSOL Multiphysics 5.2, there is a new Smooth option, which is now the default setting for the "Element nodes to fulfill expression" list in the Filter node's Settings window. Using that setting, you get much smother "filtered blocks", for example, even when the computational mesh is coarse.
