There are two possibilities. The first is to compute the thermal mass of the stuff and set that value as the thermal capacitance of the Type56 zone (I assume you are using Type56). This option assumes that the air of the zone and the stuff in the zone are always at the same temperature. If that is not a good assumption and you want to characterize the air and the stuff as having different temperatures then you might look at the TESS Loads and Structures library where you will find a lumped capacitance model. Again, you'd compute the thermal mass of the stuff in the zone and set the lumped capacitance accordingly. However, the lump and the zone would then impact each other by means of the temperature of the space (passed from 56 to the lump) and convective and radiative energy gains (passed from the lump back to Type56). kind regards, David
