Re: [TRNSYS-users] Adiabatic boundary wall in TYPE56

[David Bradley <bradley@tess-inc.com>]

Dear Xavier,
  With a BOUNDARY wall, you have the option of defining the
temperature on the other side of the wall as "userdefined"
(either an input, a constant value, or a schedule) or as
"identical." To define an adiabatic wall, simply set the
boundary temperature to "identical"
Kind regards,
  David
