[TRNSYS-users] problem with type 109 (user+standardformat)

By deleting the connection between the calculator and Type109, I was able
to produce the same results.  I think the problem was that the azimuth
angle was to be input as a string, yet you had it connected from your
calculator in degrees.  Simply deleting the connection took care of this
to yield the same results.  However, I do recall a caution that David
mentioned with using strings as  inputs.  Using a string as a parameter is
fine, so I think the case of azimuth angle input of Type109 will also be
fine because that input does not change.

Dear Matt,

Thank you very much for the reply. Please find attached the zip file which
the *.tpf files
and result files of 2 examples. The test1.tpf is the original
(problematic) file.
Test2.tpf is the
same file in which I just reset the number of surfaces that type 109 will
read to 6
and then back to
8, and I re-connect the outputs for these 2 surfaces with the unit

If you read both result files you will see what I mean. Results2.text shows
reasonable values for
Ibeam for the specific surface throughout the year, but the results1.text
wrong values. Please
let me know what you think. I am not sure yet whether it is a mistake of
mine which
I cannot spot,
or it is a problem with type 109. Please keep in mind that I have the same
in models which
contain the user-format type 109.

I am using  the TRNSYS 16.01.0002 (v.

Best Regards

Dear Eleni Ampatzi,

I could not see anything wrong the Ibeam and Type109.  What do you mean
that 'you will get the wrong results' with the Ibeam on surface 7?  The
Ibeam seemed nominal for that surface.

Dear All,

I have noticed that there is a problem with type 109. Please find attached an
example. If you try to
read the Ibeam of the surface 7 you will get wrong results. If you reset
the number
of surfaces that
the component calculates to e.g. 4 and then you reload the rest 4 and
them with the other
components, then the output of Ibeam is correct. I do not understand the
behind this. I have
24 models and I have the same problem with most of them. Any ideas? Thank
you in

Best Regards
