Plate and tube heat exchanger simulation
 

Dear

I am working on the flow simulation of heat transfer in "Plate and Tube HX" in Fluent (Will use this idea for Shell and Tube HX simulation)

I have created the model in CREO-PTC s/w and imported the ".stp" ; ".x_t" and "igs" in the Fluent module of Ansys.

But while Going to "setup" of Fluent, it is showing the error of "Unassigned Interface zone detected".
I had created the Named Selection of Interface, [/B]Inlet, outlet as it required for flow simulation. But do not know whether the problem is with Missing feature of imported file, if any.

plz suggest me some solution to this.

Thanks in advance
