Re: Trnsys 15 and 15.3

[Michaël Kummert <kummert@xxxxxxxxxxxxx>]

Dear Marco,

The bug fixes and enhancements are listed on the TRNSYS website:
http://sel.me.wisc.esu/trnsys (go to "TRNSYS Fix List")

Some bug fixes actually change the results of a simulation (hopefully 
the new results are "more correct" than the old ones). In your case, I 
assume the new results from a type go outside the acceptable range of 
some function (e.g. zero or negative input to the "log" function).

If you have a Fortran compiler, it should be easy to identify the 
problem using the debugger. If you don't, you can try to identify the 
component that causes the problem using the "TRACE" command. You can 
also remove components until the problem disappears.

You are right that the .BLD file format changed (it actually changed in 
release 15.2.07). You just have to re-open the original building files 
(BUI) and generate the TRNSYS files (INF, BLD and TRN) using the new 
Prebid version.

I hope this helps,,

Michaël Kummert
