Re: error running type56

[Michaël Kummert <kummert@xxxxxxxxxxxxx>]

Dear Arturo,
usually that kind of error happens when you have a wrong connection in 
TRNSYS, e.g. if you have a very high incident radiation on the surfaces.
I would recommend that you check all connections to Type56 and make sure 
all input values are physically possible. You can use the "trace" 
command to identify a possible misconnected input or non-physical input 
values.

Regards,

Michaël Kummert
