Thank you so much, I used DM for volume extract.
and now I have another situation: I do not know how to define the walls of the fluid in mesh since they are merges with leafguard (the middle web)(follow blue circles), the side walls are ok but not the front and back

You can pick the faces and give them a label (Named Selection). You'll need to do that with all of the walls you want to have a unique label. More critically, where does the fluid get in and out?

Hey Rob
thanks for the reply, input is from top and output from bottom
is it only for unique lable or later in settings I can add wall boundary easily?
please look at the left side of green photo (inside the blue circle) should I select all the surfaces is going inside?
I want to select the middle web area as porous zone but since from left and right it is connect to walls I do not know how to separate them

[Rob]

If you want a porous zone it's a cell zone (volume) condition, and you won't need the grate. You may find it easier to pick the main walls, and then hide those faces: then box-select the grate.

Thanks but I do not still know how i should treat the end connections of the grater and the walls, they are connected through grater

[Rob]

You need to decide which bit is porous media and which bit is solid. That comes down to what you're wanting to learn.

Thanks Rob, I will see, I might come back to you for some other tips.
