This is definitely a problem and is being worked on. When you selected the CondFD solution, that triggered an initialization routine specific for that solution technique. The problem occurred in part because you used regular materials for the air layer rather than Material:AirGap. The CondFD code was basically going through all constructions and even ones that were not using the CondFD solution. That included one that had your air layer in it and this caused a problem. If you had used the air gap input rather than the regular material input, it would have skipped this and you wouldn't have gotten an error message. So, that is a temporary work around--change your air layer definitions to Material:AirGap. The full fix is to skip constructions that are not used for CondFD and that is what is being worked on. Hope this helps!
