Hai, im currently using energy and interface method to simulated my heat exchanger model. however when i tried to use heat exchanger method to solve it. i receive a warning saying that the zones are not overlapping. i tried to figured out how to make it but not succeed. i couldn`t find anything helpful at the ansys fluent guide as well... it says we can make 2 line or area or volume to overlap with some command but it didn`t guide the way to do it... can any1 kindly help me with this??? how to setup overlapping zone?? in my case there will be a shell>external flow>tube>internal flow
