Hello all,

I am currently working on a U-Pipe ETC project on ANSYS Fluent to investigate the melting/solidification process of the working fluid integrated inside the U-pipe. The first image attached is the top view of the current mesh that I have generated. 

The reason why I made the U-pipe as a single body (which composes of 5 different bodies) is so that I can have more control over the meshing of the U-pipe as all the critical parameters that I will be analyzing is within int U-pipe. The other circular geometries are the Evacuated Tube Collector parts (outertube, vacuum region, innertube, fin, etc). Hence I have two separate bodies now: Body 1 is the Upipe while Body 2 is the ETC parts. 

The problem with having two bodies is that my elements and nodes are not connected between the two bodies (see images attached as follow

(Cross-sectional view of the mesh) 

Is there a way in Fluent Meshing that allows me to "combine" the 2 bodies so that I can have my elements and nodes connected between the two bodies? I have tried making the the Upipe and the ETC parts as "1 body" in the Geometry, but that will further pose a problem for me when I am defining my boundary conditions for the Upipe in the Fluent Solver.

Any tips and advice are greatly appreciated.

You've not split the model in the geometry tool. Do that and then check the documentation for "share topology".  If you click on help you'll find some tutorials that'll take you through the process.

Hello,

I tried Shared Topology and it's still meshing as if it's two different bodies (like seen in the picture attached in this post). I'm not too sure what i did wrong, do you have any suggestions on how to move forward?

Thank you so much for your time and help,

Hi Sir,

I tried Shared Topology by following the videos attached and it's still meshing as if it's two different bodies (like seen in the picture attached in this post). I'm still not too sure what I did wrong, I suspect it might be something to do with my geometry. Do you have any suggestions? 

Thank you so much for your time and help,

To have conformal mesh you need to have bodies in the same part. then use share topology. 

if you have bodies in different parts, you will not get connected mesh after share topology. 

please check no. of parts in you geometry in DM.

Hello all,

I figured out the issue is within my geometry itself in DesignModeler and have fixed the problem. Thank you all for responding! I appreciate it!
