Hi all,

I am attaching my geometry, I have a surface body in the middle (points-lines-surface). I have to subtract this surface body from the rest of fluid domain as I have to give different boundary conditions at the bottom so I need three faces at the bottom: two from fluid domain and one from the surface body. 

when I use boolean operation although it is done but I do not get three faces at bottom, I have just one like at the start.

Is is possible to subtract the surface body from the rest fluid domain?

Regards

Is it suitable to use boolean-Imprint faces?instead of boolean-subtract?

Use Imprint. Boolean won't work as the surface has no volume to overlap with the fluid region.

You can use imprint. 

Or you can create a single part of surface body and solid body and then use sharetopology.

Thank you very much for your kind replies, for my case imprint goes well because by share topology I am unable to select the faces separately for different boundary conditions.
