making curve from a plate

Hi all

   It is a while that I am dealing with drawing the heater rin my office but I faced with a problem. Here I have attached what I have made so far. I can not curve the honeycomb flux in a way that it can be attached to the body of the heater. I would be thankful If anyone could help me with it. I also have attached the real picture of the heater to give you a sense that how the should be attached.

Cheers

Hamid
