  Hi,
I tested calculation the Conduction heat flux from the wall at the
outsideside surface (qso) and Conduction heat flux from the wall at the
inside surface (qsi) with the coefficients of transfer given by TRnbuild
but I do not obtain same the results as TRNSYS by comperant them with
QCOMI (NTYPE 19) and QCOMO (NTYPE 19).
is what you can help me?
best regards
