help!cannot use assembly mesh&multizone at the same time
 

Hi, everyone, I'm new to AnsysMeshing and have some problem with the assembly mesh.
I have several irregular sweepable bodies in a fluid domain, and I want to use multizone or sweep mesh method for these solid bodies;
while the Cutcell assembly mesh for the huge fluid domain(which is a boolean intersected body).

The problem is when i turned on the Cutcell assembly mesh method, the multizone mesh method become invalid.I can either use Cutcell for both the fluid domain and inner small solid bodies, or, use multizone for them.

Though I tried defining virtual body for the fluid domain with surfaces, ANSYS Meshing always told me there's a leakage and meshing was not successful.:(

Can I use Cutcell and multizone\sweep method at the same time for different bodies?
Or how can I fix the leakage problem with the virtual body?

.....Anyway the question is a bit long. Thanks for your time....:)

split geometry in appropriate topology and you can do it through multizone or sweep method.

thanks for the tip. actually I have tried cutting the domain just above these small bodies to make all the domain sweepable. But this will result in too many cells. So is there any way to cut down the number of cells if i use sweep method for all the bodies?
