[TRNSYS-users] Mismatch between view factor matrix file and BUI file

[Damien Gondre]

Dear Trnsys-users and developers,

I found a solution to my problem thanks to a french trnsys-user who
answered me. So please don't take into account my earlier message.

If someone experience the same problem, look at the "Building Geometry"
extension at the end of the *.bui file. There were a lack of information in
my *.bui file (some zones were not described in this section. Consequently
the VFM matrix couldn't be properly calculated). I could explain where the
problem came from but it was my mistake :)


Thank you,

Damien.
