[TRNSYS-users] solar heating

[salima adjiri]

hi all,

 actually on solar heating system using rock bed storage, i had when
trayin to lunche the simulation the message I found in the list file
was : " Message   : The rock bed thermal storage component only allows
flow in one direction at a time. Positive flow into both the top and
bottom of the bed were specified."

if some one have an idea about this please help.

thanks
