I'd go back to the geometry tool and either share topology (SpaceClaim) or create a multibody part (DesignModeler). Otherwise the interface zones will be created in Fluent and you'll need to check they're correct there. You then have all the fun of nonconformal fluid-solid boundaries. Nothing wrong with them, but if you don't need them it's easier to avoid their use.
