[TRNSYS-users] Air layer in Trnbuild



Hi Trnsys users,

I am trying to create a model of a lightweight contruction sport hall, which consists of two leyers of special Polyester foils, and a 70cm air layer between. In reality, the construction is streched and held in place by a wood sceleton.

I have noticed, that whichever air layer is chosen from the library, it is modelled as massless, and the tickness is 0.

How can I change the tickness of the Air layer?

In addition, I get the following error messages when I try to save the project "error when trying to create wall transfer coefficients"
" unable to find root, after indication that root exists"
"Maybe time base is to small"

What could be the couse of the error I am getting?


Thank you for helping!
