I am trying to simulate subcooled flow boiling inside a tube using Eulerian Multiphase RPI model. There is solid wall (steel) and fluid domain (water-vapor). I created the mesh and imported in the Ansys Fluent.

But, Fluent considers the solid steel as mixture (of phase1 and phase2). How do I properly define these solid-fluid regions/interfaces?

The screenshot of cellzone attached. The mesh settings are also attached.

(I know I can do simulation without considering solid part, But it's kind of important for me because further simulations will required conduction in Fins).

Dear MarcusAurelius,
I do not have Fluent open so i am not sure.
I think you have two domains in your Fluent configuration (fluid and solide), is not it ? Can you see the solid domain in your post-processing options ?
Basically, i am not sure that the "mixture" phase you saw means that Fluent consider it as a mixture of phase 1 and 2...



Best regards,
Pierre
