I want to simulate the wind passing through the air-conditioner. There are two tubes passing through many thin plates,and cooling the thin plates and wind.The thin plates aslo cooling the wind. It is very hard to mesh them. when i try to mesh them by automatic method, there are some negative volumes. so how can I mesh a model like this. Attachment is the picture of the model.

I would like someone can help me, thank you very much.
