3ply laminated timber( IBP WUFİ materials) different water content diagram

[beggy]

Hi ,
I am student from University of İstanbul Tecnical and currently conducting a master thesis project. I use WUFI 2D.4.1 to simulate the Cross Laminated Timber wall for Istanbul climate , I edit 3ply laminated timber( IBP WUFİ materials),however simulation result the attached diagram shows still a sudden rising of the water content from 100 to 350 kg / m³ or 20-70%. This is not realistic. What should I do? I use similar materai such as STORA ENSO or KLH massivholz material but this diagram not sudden rising of the water content.What is the cause?Numerical grid 120x120,initial conditions EN15026,time step 8760 one year

Hi Beggy,
looks like your timber is exposed to rain. Can you please post a picture of your construction and your transfer settings.
