Re: [TRNSYS-users] type 56 with TrnOpt

[Michaël Kummert <michael.kummert@gmail.com>]

Gilles,

As Jeff says, Genopt will allow you to optimise parameters within Type56
if you skip TRNOpt. Genopt is very flexible and allows you to optimize
parameters in several different input files, e.g. the TRNSYS input file
(DCK) and the building file (BUI). And TRNSYS version 16 automatically
calls TRNBuild at the beginning of the simulation to refresh the
pre-processed building data files (BLD and TRN) using the latest version
of the BUI file, so any change in the BUI file will automatically be
used in the simulation.

I will send you off list a working example that might help you tweaking 
the Genopt configuration files and the TRNSYS input files. The example 
also shows how to use equations with parameters in Genopt (e.g. you 
might optimise a window height but you need to write the window and wall 
areas in the BUI) - another thing you cannot do in TRNOpt as far as I 
know. If anyone is interested, just let me know.

Using TRNOpt would of course be much more convenient... A new feature
for the TESS libs V3?
