The bottom boundary condition is set by lbound and TDEEP. By default, the interfaces sets a fix bottom temperature:
lbound = -1.//180.

Heat Flow
A geothermal heat flux can be set using lbound alone, with the heat flux given in mW/m2:
lbound = 35.
set a heat flux of 35 mW/m2.
Insulation
lbound = 0
insulates the bottom layer (no flux)
Set Bottom Temperature
The bottom temperature must be set first by TDEEP, then a flag is provided through lbound:
TDEEP = 180. #Bottom temperature set at 180.K lbound = -1//TDEEP
Set the Initial Temperature of all the Layers
TDEEP = 180. #Bottom temperature set at 180.K lbound = -2//TDEEP
All the layers are initially set at TDEEP. DOES KRC KEEP TDEEP AS THE LOWER BOUNDARY CONDITION?
