ANSYS FLUENT fluid body recognition problem
I am a student beginner in ANSYS.I am trying to simulate the hospital room ventilation. I designed the fluid domain in solidworks by converting the assembly to sldprt and then using combine (subtract) option. The sectional view shows hollow in the occupants areas too. But in ANSYS geometry it recognises the occupants as solid bodies and meshes these regions too. I need the occupant surfaces as walls for boundary condition. Suppressing these solid bodies also suppresses the walls in design modeller. How do I retrieve only the fluid domain and tha surface for walls? Do I make changes in design or in analysis?
