Hannes, Type 56 checks the energy
balance every iteration step and gives an error if the error isn’t lower
than 0.002%. Since it stops at the
beginning of the simulation maybe your inside surfaces temperatures are almost
the same and thus the total energy
exchanged is very low and from a very low value ... . Unforunately, you can’t
really the initial inside surface temperature of each surface. However, you can try to
set the initial value of the temperature for boundary walls to value different
than 20 °C. If you still have trouble
we need to have a deeper look into your project. However, please don’t
send the project to user list but to hotline@transsolar.com.
You need to include your
TRNSYS licenses number and your university / company. Von: Hannes Oppeel
[mailto:hoppeel@hotmail.com] Hi everbody! I'm currently modeling a church in the Sketchup plugin to
evaluate the stratification and the comfort at different locations in the
building. I've succeeded to import the idf-file into trnbuild without
errors and when I turn on the detailed radiation mode in trnbuild I have no
problems to generate the view factors matrix( after a long proces of trial and
error). The problem is, when I try to simulate the building in the
Simulation Studio I get the following error: "Internal error of detailed longwave radiationexchange
of zone 1 . Energy balance error of 0.002 % at time
5.00" I have no idea where the error might be coming from... Any advice would be greatly appreciated! Hannes Oppeel |
