Hi,
I am currently using both WUFI Pro and WUFI 2D. To validate my model in WUFI 2D, I have created the exact same building envelope assembly as in my WUFI Pro model.
Although the interior and exterior climates, material properties, and initial conditions are set up identically in both software programs, I am getting different water content levels, especially i dont understand why in the exterior LP SmartSide siding material the result are not the same despite the exterior climate are the same. While the temperature profiles match closely across the envelope, the water content shows noticeable discrepancies.
Could you please help me understand why the water content is not the same and how to resolve this?
Additionally, is it theoretically possible to get the exact same results in WUFI Pro and WUFI 2D if all parameters are identical? Does this discrepancy typically depend on the numerical mesh generation, or are there underlying differences in the calculation engines for 1D vs. 2D transport?
Thanks in advance for your help!
