HVAC System, NICU

Hi, I am new to simscale and I am used to creating named selections for faces on ANSYS etc when setting walls, inlets and outlets. I am trying to set the area within the enclosure box surrounding the incubator to a closed internal region but I am getting this message. I imported the incubator and the enclosure as an assembly. I’m wondering if this step even needs completing if I’ve created the enclosure outside of simscale, I hope somebody can help. Thank you in advance.

Also, the boolean subtraction failed

Hey, this is because your walls do not have thickness, so it is not possible to select the inner face of the wall to define the internal region, does this make sense?
