Re: [EnergyPlus_Support] Using HAMT model

["jeannieboef@xxxxxxxxx" <jeannieboef@xxxxxxxxx>]

Sorry. IR Material does not work with CondFD or any other. You have to asign the CTF algorithm to it.

Hello,

Since this virtual wall is not a real wall and it is only there to separate my initial zone into two subzones due to their thermal load differences.

However, when I got to specify the moisture settings in MaterialProperty:HeatAndMoistureTransfer for the Virtual Wall that used IR Transparent Object as said, I had repeatedly severe errors in the ouput. Below is the severe error:
