Error report

Hello Everyone
I tried to run my simulation and keeps giving me this Any help

Error
Surface temperature instability in room 100009. Possible remedies: add thermal capacity to construction STD_ROOF; reduce time step; set control radiant fraction to 0, check gain and ventilation levels; reduce Macroflo opening areas.


Thanks

Hi,

Quick one just now to get you started, you can check aspects of your model in case there was an error on the thermal data or perhaps with your geometry.
