Importing ANSYS Speos Heat Flux Data into ANSYS Fluent

[t.badawy]

Hello everyone,

I am currently working on a project that involves coupling ANSYS Speos optical simulations with ANSYS Fluent thermal analysis. My goal is to import the heat flux data generated in Speos directly into Fluent for a conjugate heat transfer study.

I am looking for guidance on:

The correct workflow to export and map Speos heat flux data onto Fluent geometry.

Any specific file formats or settings required to ensure proper data transfer.

Common challenges or pitfalls to avoid during this process.

If anyone has experience with this workflow or can share tips, I would greatly appreciate your insights.

Thank you in advance for your support!

Are you needing to run a coupled calculation or is this a one off transfer? Is the heat being transferred to a wet (adjacent to the fluid) wall, or to the "outside" of the Fluent domain?

[t.badawy]

 

In my application, which involves a solar parabolic trough, the heat flux from the optical simulation will transfer through the wall thickness to the water fluid inside the tube. Therefore, the heat is applied to a wet wall adjacent to the fluid domain, and my goal is to perform a coupled thermal-fluid calculation to capture the conjugate heat transfer.

I believe is one time transfer

So, you're getting Speos data at the outside of the metal tube? We can then include the metal as a solid or use a thin wall. Either way, Fluent wants data in a "Profile" format, with position and either heat flux or temperature. Heat and flow are coupled in Fluent (it's a normal application) my question related to whether the Speos>Fluent data transfer was a one off or if you need to feed data back to Speos. 

[t.badawy]

Yes, the Speos data corresponds to the outside surface of the metal tube, and I plan to include the metal wall in Fluent for the conjugate heat transfer analysis. This will be a one-way transfer only, and I do not need to feed any data back into Speos.

OK, so you need to look at profiles for Fluent, in summary they're position and value data sets. I assume Speos can write out something equivalent which may need a little manipulation for use in Fluent. 

[t.badawy]

Yes, the Speos output is indeed a text file containing XYZ coordinates and heat flux values, and I can manipulate it to match Fluent’s profile format.

I would greatly appreciate it if you could share any sample files, links, or tutorials that demonstrate how to properly map Speos-generated heat flux data into Fluent boundary profiles.

Funnily enough we have manuals.....  https://ansyshelp.ansys.com/public/account/secured?returnurl=/Views/Secured/main_page.html?hl=f
