I performed a simple simulation (see the attached file), where a part with two holes is included in a englobing domain. The two half-circles at the base of the englobing domain allow to insufflate and extract the fluid in the domain. When I use the englobing domain, I have this error:

2 isolated fluid regions were found in domain Default Domain

If the isolated regions do not have the pressure level set either
by the boundary conditions or using a reference pressure equation,
you may encounter severe robustness problems.

This situation may have arisen because a domain interface was not
properly defined during problem setup. Please carefully check
the setup.

That's strange because I am pretty sure all surfaces are defined like walls, In or Out. I only used proximity and inflation options to generate the mesh.

Have you already observed this error with the englobing domain ?

How can I solve this error ?

Thank for your help
Best regards
JF

Set up domain interfaces.
