2nd type boundary conditions

Hello,

Is there a way to define a second type boundary conditions in WUFI 5?

Thanks in advance!

Hello janeksjr,
What do you mean with second type boundary condition?

I'm putting a phase change material (PCM) on the inner layer and want to know how it stabilizes the temperature inside the room compared to similar material without PCM inside, so I don't want to set the temperature value, but rather give a heat flux through the construction.

Thats not really good to handle with WUFI Pro.
WUFI Pro only allows to export the heat fluxes after calculation. But as the temperature is a boundary condition, you can not see the influence of the changing material.

Have a look on WUFI Plus, there you can calculate the indoor conditions depending on the outdoor climate and the envelop.
