Hi all...

I need help to generate the mesh interface between surfaces.

I'm doing heat transfer analysis of 2 heat exchanger by placing it under a domain.

The flow of primary fluid ( air ) is in same direction for all heat exchanger whereas for secondary fluid ( coolant ) differs.

I have attached pictures regarding the geometry.

Air flows in -Z axis while coolant flows in -Y axis ( 1st heat exchanger ) & X axis ( 2nd heat exchanger ).

Please help me in giving mesh interface. Because i'm getting floatation point error.

Thanks in advance.

modify the air domain to the extent of inlets and outlets of both the heat exchangers. Side walls surfaces should be in line (both surfaces in same plane) with inlets and and outlets of heat exchangers.

Thanks Mr.kiran..
Since i'm new to ansys, can you help me in doing interface ?

Please send me your mail id. I will send you the file.

make the boundary/domain as shown in the attached image, I have drawn those line assuming it as a top view.

Should i make it as a single part or multi parts ( HX1, HX2, domain ) ??

yes, you need to make three.
