Hello,
I'm rather new to CFD, and I'm really new to COSMOS FloWorks. I'm trying to make an analysis of a ventilation system. The system is to be used in stables, and the warm air from the stable is led out through a fan. This causes the pressure in the stable to decrease, and fresh air from the outside is drawn in through openings above the ceiling. The ceiling is made from a porous medium, so the air is drawn into the stable. The point is not to draw cold air directly into the stable, but let the temperature rise first.
My model contains of walls and floor, the roof and an outlet. Between the roof and the floor is a porous medium. The air in the stable is modelled as a fluid subdomain with different initial conditions. When beginning to solve the problem, I get the warning "Unresolved region" "Condition name: Fluid Subdomain 1". What causes this, and how does it affect my analysis?
The fluid subdomain is modelled as a solid that has been disabled.
Thank you in advance.
Best regards
