The black area is the area that i would mark. How can i do it??
In a simple geometry I follow this steps:
Adapt -> Region and then i set the min and max values. In my case I have a complex geometry. If I proceed with the similar method that I use for the simple geometry, I obtain only upper black region and empty in the bottom.

Can you explain what you mean by marking of the geometry?
If you mean different volumes, then you can make the geometry in such a way that you don't unite all the volumes. You just have to stitch the joint faces of different volumes.

Hi,

First of all I would excuse me for my English.
I try to simulate a fluidized bed reactor 3D and I have a complex geometry. Before I proceed to calculate my solution (unsteady) I must mark region of my geometry and so how to do it? -I've complex geometry and i don't know if is possible to mark two different regions in same time. I hope someone help me.
