Hello I'm Rain,
I need some major help. I have a senior project and I need to display a flow simulation of air for two different roof materials that will have a radiation form the sun and convection and I want to displace the temperature of air as it goes pass these two surfaces I have been trying it internally and externally and I either keep getting error or I keep getting everything the same temperature which is not true. I search all tutorials about flow sim and they suck. Mines couldn't be more simple its model of 100x100 in flat plate please help me!!!!!
