[TRNSYS-users] massive buildings

[Eunice Vilaverde Fontão]

Thanks, so you believe that by increasing the timesept the results  
will be more accurate for massive walls.

I am using 1 hour for timesept because it is easy to deal with the results.

Still I tkink that Trnsys is not very accurate for massive constructions.

Best regards
Eunice
