Hello,<\/p>\n

I have a finished simulation with the attached domain. used mixture model, lee condensation\/evaporation with piece-wise linear for saturation temperature of humid air. ran for 250s and converged.<\/p>\n

Initial Condition: Chamber at 15C with 80% RH<\/p>\n

                           Air inside the pipe 17C with 80% RH<\/p>\n

                           Soil and pipe at 17C<\/p>\n

Final Condition: Chamber at average 20.48C with 0.66% RH<\/p>\n

                          Air inside the pipe at average 20.19C with 0.67% RH<\/p>\n

                          Soil and pipe at average 17.09C<\/p>\n

 <\/p>\n

My questions are:<\/p>\n

1-How the average temperature of soil went up not down?<\/p>\n

2-When calculating MASS INTEGRAL of TOTAL ENERGY and selecting all parts, should not the initial and final values be the same? these values are not similar in my simulation!<\/p>\n

3-when calculating MASS INTEGRAL of TOTAL ENERGY for ALL PARTS EXCEPT CHAMBER, I expected the difference between initial and final values to be equal to the energy added to the Chamber part, but its not the case! what am I missing?<\/p>\n
