The error message is indicating that the energy balance across one
of the walls in your Type56 (I am guessing) building is not
converging. Specifically, the outside surface temperature of the
wall is not coming to a stable solution. If you are using an
algorithm to set the convection coefficient on the outside surface
of your wall, make sure that the algorithm cannot produce a result
of 0; this would indicate that there is NO convective heat transfer
on the outside surface of the wall and that only the radiation
matters, which is unrealistic. The second thing to try is that if
you have variable convective coefficients on either the inside or
the outside surface of that wall, turn them off and use constant
values.<br>
Kind regards,<br>

<div>I have a mistake during a simulation, an eror occured

<div>I don't uderstand the mistake because I've two models:</div>
<div>One with a building and convectors and it works, another with
the same buildind, convector and a wood poele ans it doesn't
work</div>
