Fenix+ allows you to measure the effects of a simulated fire on the object surfaces.
Without this option turned on - data on heat flux and surface temperature will only be save for objects of flammable material, which are placed in a separate Building that do not have a Fire Source placed inside of it. Such scenario is possible with the Master Plan setup, to measure fire from one building affecting the other building.
Enable dangerous fire factor measurement
To measure OFP on the surface of other objects, select the desired object on the scene and check the Measure dangerous fire factor on surface box in the properties of that object.

View results
To view the calculation results, run a Fire Dynamics Simulation and go to the Results tab.
The object with this parameter enabled will be displayed in the object list on the Heat Flux and Construction Temperature tabs. Detailed explanations of the results could be found in section: Fire Dynamics Simulation Results.
