For the boundary values I used converter.getLatticeTemperature(298.0). At the surface, depending on the configuration of cells, I found between 296.5 and 300 at the fluid cells. And some points of the boundary, those which are more exposed to the fluid due to the stairway shape, have a value of 302. Sorry I did not understand your third sentence. If I refine the mesh, it reduce the fluctuations but they are still there.
