For solid-fluid coupling problem. there are two faces generated by Fluent: say, WALL and WALL-Shadow. Now, I wanna know which face does refer to fluid? WALL-Shadow?

And, the absolute value of heat-flux through these two should be the same? But I found a very small difference, NOT extractly identical. Why?

Other Variable should be identical?

Hi!

for me, it seems to be, that fluent sets WALL and
WALL-Shadow more or less random to the fluid and the solid.

I am sure, there is a system, but I don't get it.

I see, that there is no heat flow on the surface related to the solid. Also, the yplus value is zero at that face.

Best wishes
Ralf

Under boundary condition, click any of those 2 walls to define boundary conditions, and you will see it will tell you on the new pop up panel which zone (solid or fluid) it belongs to.
