WUFI® 2D:  Some constructions cannot be modelled accurately by one-dimensional simulation. In these cases two-dimensional calculations with WUFI® 2D should be performed. Application examples are:


– moisture conditions at structural and geometrical thermal bridges – especially if the hygrothermal conditions inside the structure and not only on the surface are evaluated

– simulation of joints, connections and corner details

– timber framed constructions with multiple insulation layers

– building components with anisotropic materials

– three dimensional simulation of punctual penetrations with radial symmetry.

The input in WUFI® 2D and also the calculation is in comparison to WUFI® Pro more time-consuming. As far as two-dimensional problems can be solved one-dimensionally (incl. simple approaches for ventilation and rain water leakages) the simulation with WUFI® Pro is normally easier. Generally WUFI® 2D should be used in addition and not as an alternative to WUFI® Pro.

WUFI 2D Workshop -

Prerequisite:  WUFI Pro.  

2D simulations are required to evaluate the hygrothermal performance at thermal bridges, joints, foundations, corners, etc. The WUFI-2D Course includes hands-on project work and practical application cases as well as information on material anisotropy and differences with 1D simulations.  

WUFI 2-D 2012 (2-dimensional simulation, prerequisite is WUFI-ORNL / WUFI Pro):    

    WUFI 2-D and Advanced WUFI 1D  2-day Workshop:  February 4-5, 2013; Napa, CA.  This is the most comprehensive WUFI 2-D workshop offered in years (this is 2 days; last year was 1/2 day).  Cost:  $945.00.
