How to simulate a large scale body?
 
Hi there, I want to simulate the ventilation and heat transfer in a very large building. I want to know how to make a small model using FLUENT? What principle should be used to diminish the large body to a small model? Thanks.

Hey: I did this work before. You just need to know waht is your Rayliegh Number, Reynolds Number, Prandtle number. That's it you can make it. You just need to fix these numbers. If they are fixed you are solving the same problem. Don't worry you can apply the real dimension but play with material properties to fix these numbers. Let me know if you still have a problem. Thanks/Farid
