Hello,

Metal box made of Iron and inside air trapped. Top surface exposed to direct sun light. Cu pipe installed and fresh entered to inlet. I want to measure outlet air temperature. I added two fluid subdomain for trapped air in the Iron box and air for Cu tube. But solver gave me following warning messages, Can anybody help me to sort this warning. I made cut plot but it didn’t show the air temperature section inside the Iron box.

Thank You,

Janitha
