Hello,


System Coupling requires 3D meshes and cannot exist with 2D mesh. Please refer to the following section of the Users guide to understand this better.

If you are unable to open the User's guide, please take a look at the following link.

If you are looking to transfer heat from between two solids or a solid and a fluid, please ensure shared topology is applied properly. This should create a wall and wall-shadow. You should be able to use the 'Coupled wall' in Fluent to model these scenarios. Please refer to the Fluent User Guide for more details.


I hope this helps answer your question.


Thank you.


Best Regards,
Karthik
