Model used for the computations of the 2D THM backanalysis
Simple model:
• isotropic (conductivity, permeability, rigidity)
• no gallery temperature

Conclusions
The non homogeneous seasonal temperature variation in
the gallery has a non negligible influence. It is important to
keep the sensors in place after dismantling.
Keeping heating during some months is attractive to
investigate the possible influence of the recent low gallery
temperature.

temperature and temperature distribution
