Hello,
I'm doing sensitivity analysises in the same way as Hilde (with
Matlab), if you want an example of the matlab-file, I can send it to
you, Beatriz.
But I also ran into a problem:
I want to use my data-files from type 25 as an input in my next run of
trnsys, but there is always a header line in the type25-files. This
data file is 8760 houres, i.e. one year long. I don't have any problems
when my simulation is one year aswell; I just let the data reader skip
the first line. But when I want to run more years in a row, the data
reader doesn't skip the first row anymore and an error is produced.
Does somebody know how I can get rid of the header line in trnsys ? or
how to skip the header line when the second year is started ?
And something else, does somebody know how to put TRNSYS the whole in
time in low priority, i.e. before it starts running ? Everytime it
restarts for the analysis, I have to open the task manager and do it
again.
Best regards,
Jeroen

Dear Beatriz,
I'm working on a sensitivity
analysis too (to identify which parameters have the greatest impact on
thermal summer comfort in a building that is cooled by natural night
cooling). I control the simulation process in Matlab to prepare the
input files for Prebid and Trnsys and to run these programs too.
to run Prebid from an other program:
rename prebid.exe bid.exe and use
command line:
\Trnsys15\prebid\bid.exe
name_of_file.bui
to run Trnsys:
\Trnsys15\\trnsys.exe
name_of_file.dck /n
If you have more questions, you can
send me an e-mail directly.
best regards,

sensitivity analysis
Dear
TRNSYS users,
I
am trying to perform a sensitivity analysis to identify the parameter
to which indoor air Tª is most sensitive. I am
specially interested in a number of particular parameters. Is there any
capability implemented in TRNSYS, which could help to develop this kind
of analysis.
Thanks
a lot in advance.
Best
regards, Beatriz.
