Hi, I was wondering if it's possible to use as constructions of the airflow window, a glazing defined as a complex fenestration. I tried to implement it but i get an error message that i can't fix: "Gas type not air in airflow gap of construction".

The gas type (defined in WindowMaterialGas) it is air but to be able to insert it in the complex fenestration construction i have to define it as WindowMaterialGap, and somehow the airflow doesn't recognise it.

Thank you.
