[TRNSYS-users] Ground back heat transfer coefficient

[NALIN SWAROOP]

hello all

Why does trnsys gives a very large default value(999) to the back heat
transfer coefficient of the ground layer?what does large value signify?
and as  ground is defined as the boundary should'nt just the boundary
temp. value a sufficent input??

I have kept the value to be small(<.001) and large (1000) but there are no
changes in the results.

TIA
