Hello,
i want to ask, it is possible to simulate drying influenced by airflow ? ... there is only one point... surface exterior coefficient depended on wind. but when i use different wind ( 3 m/s or 30 m/s - created by excelclimate) there is no change in my results, is there any way how to simulate this situation ? ... can you help me ?

Re: drying influenced by wind
Hi palino1,
WUFI assumes that the vapour transfer coefficient at the surface is proportional to the heat transfer coefficient. So if the heat transfer coefficient is set to wind-dependent (and if there are actually variable wind data in the weather file) the vapour transfer coefficient will automatically be wind-dependent, too.
You can see the variable hourly values by using the ASCII-Export (in the Outputs menu) to export the "Vapor Transfer Coefficient (Exterior Surface)" or the "Vapor Transfer Coefficient (Interior Surface)" to a text file. In the dialog "Options | Export Format..." you can choose to add a Header Line which shows you the name and the units of each column.
Kind regards,
Thomas
