Hi, I am working on a TPMS geometry and I would like to evaluate the pressure drop and the outlet temperature of an air flow through a gyroid unit cell.
I followed the tutorials on conjugate heat transfer and on the gyroid heat exchanger. However, in my case I would like to model only the fluid domain using implicit surfaces, if possible. I did not fully understand whether this approach is supported.
As an alternative, I tried to create:
- an internal flow channel with a square cross-section (modelled as a solid boundary),
- an implicit gyroid surface as an embedded solid,
- and the remaining region as the fluid domain (capped with the apposite function into the fluid workflow).
With this approach, the software generates the complete volume instead of the boolean difference corresponding to the fluid region inside the gyroid structure. Because of this, I am not able to impose a wall temperature boundary condition on the fluid domain, which is required for my simulation.
In addition, the obtained solution does not seem physically reasonable.
Is there a correct workflow to generate only the fluid domain of the gyroid structure and apply conjugate or prescribed wall temperature conditions?
Thank you in advice for the support
