Hi,

The error message indicates that the pdf table bounds are reached with the model settings you are using. These cells are limited to the minimum and maximum value of enthalpy. May I know the quality of mesh you are using.

You can also try setting the maximum heat loss fraction to 1 and maximum heat gain fraction to 0.6 using tui command :
