Michela, The error is coming from Type56. When you define an active layer in Type56, the specific flow rate in that layer (kg/h.m2) must be above a certain minimum in order for the energy transfer algorithms to be valid. The error states that the flow rate in the active layer of surface 44 in your building is too low. Look carefully at the way you are setting the flow rate that comes through your network of Type11s and makes sure that each branch that feeds an active layer always has sufficient flow in it.
