Hello Ahmad, I am sorry I dont have reply to your question, rather, I thing that with the model you are working, you can help me in preparing a sketch/model of a rectangular enclosure for ventilation analysis. I want to create a room having an internal heat source and with inlet & outlet doors? Please help me in developing my model.
