WUFI

I have modeled a simple box and meet passive criteria. When running in WUFIplus scope I get an error message in red (see attached screen shot) "Only thermal calculation". What information have I left out of the model?

It's not an error: it means you are only doing the thermal calculation without moisture fluxes. In order to include them, you need to go under "case 1" and untick the option "Only thermal calculation". You will see the simulation will take much more time.

Thanks
