input. *i's cuz VEOI's in cncult.

Name	Type	Variability	Description/Comments
thk	LEN_GZ	input time	-1 or optional default thickness, ft
cond	CNDVY_GZ	input time	conductivity, Btuh-ft/ft2-F (at mt_condTRat)
condTRat	number	input time	rating temp for mt_cond, F (typically 70 F)
condCT	number	input time	conductivity temp coefficient, 1/F condAtT = mt_cond*(1 + mt_condCT*(T - mt_condTRat)
spHt	SPECHEAT	input time	specific heat, Btu/lb-F
dens	DENSITY	input time	0 (massless) or density, lb/ft3
rNom	RESVY_GZ	input time	nominal R of insulation, ft2-F/Btuh-ft = resistance of 1 ft2 per ft thick. documentation only (typically round number, e.g. 13) -1 = not given derived. *r: set in input check/setup.
vhc	HC_VOL	Start of run	volumetric heat capac (Btu/ft3-F): mt_spHt*mt_dens
