Error (2 isolated fluid regions) with an englobing domain

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.
