overlapping heat exchanger cores- as in ansys user guide
Hai, thanks for your time...
im simulating heat exchanger using ansysfluent 14.0 and i wanted to use dual cell model. the hot and cold fluid zones are not overlapping and i dont know how to make them.
According to the ansys user manual..
If the mesh file does not already contain overlapping heat exchanger cores for primary and auxiliary fluids, then you must create a duplicate of the zone that represents the core using the following text command:
mesh → modify-zones → copy-move-cell-zone
You will then be prompted to enter the ID of the zone you want to copy, and either the distance for translation in each of the axes or the rotational angle, origin, and axis.
& when i try
>mesh → modify-zones → copy-move-cell-zone
modify-zones/: Enter the modify zones menu.
?: Enable help mode. Type "q" to return to command mode
invalid command [copy-move-cell-zone]
invalid command 
i dont know where`s my mistake. i really don`t have any idea,how to respond the command. can anyone please help me with this...??
