Dear TRNSYS users: I found something very strange with type 109 user which might be a bug
of the component. Can any body who knows explain why and help me to solve the
problem? I noticed the problem when
I worked on my system using type 109-user to read one week of global and
diffuse radiation on horizontal surface. Later I found out that it is a common
problem even with the example (type109.tpf). If you have time to have
a look at it, you can repeat the problem by the following steps: 1, using Studio open the
example in folder ..\Trnsys16\Examples\Weather
Data\type109.tpf 2, change simulation
start time to 1, stop time to 168 (1 week) and run the simulation. Focus on
radiation data of Wuerzburg. No problem. 3, change time step to
0.5 hour and run the simulation again. Then you will find that there are no
radiation data imported for the first day of Wuerzburg. Is that very strange?
Why? Since I need it to read
one week data for comparison between calculation and measurement, I have to solve
the problem. Please stand up and help me if you know the reason. Thanks in advance! Jianhua Fan DTU |
