WUFI Pro vs. WUFI 2D

[Axelarris]

I have used WUFI Light, but am now considering purchasing WUFI Pro or WUFI 2D for design purposes. I am having a hard time finding enough information to compare these products. What are the advantages of WUFI 2D?

In a typical assembly, there are usually two main section types (or conditions) that I can model - through the studs or plates, and through the cavity between the studs. I would like to be able to analyze the interaction between these two conditions. Can WUFI 2D or WUFI Plus do this? Does WUFI Pro assume that the 1-D section is infinite out-of-plane (ie. no hygrothermal transfer in the "in and out of the page" direction or the "up and down" direction). Will WUFI 2D be able to apply capillary action, conduction, convective drying, etc. that occurs laterally or vertically within the assembly?

Thank you, the WUFI 2D demonstration was very helpful. My understanding is that that WUFI 2D is two-dimensional in section, so base plates, sills, headers, ceilings and floor assemblies can be incorporated into the model. However, it seems to me that studs and corner construction cannot be analyzed by WUFI 2D (since a model of these conditions would be 2-dimensional in plan view). Can you please confirm my understanding?
Thank you very much.
