<p>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).</p>
