Beatriz,
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.
If you just need to run TRNSYS with different values of some simulation
parameters, you can use the "parametric table" function in TRNSHELL (in
the parametrics menu). You can create a table with different values for
all CONSTANTS in your input file (note that if you create your input
file within IISiBat you may have to edit it to replace the "EQUATION"
keyword with a "CONSTANT" keyword).
If you need to perform more advanced parametric studies, e.g. involving
an optimization, you could use GenOpt
(http://simulationresearch.lbl.gov/GO/). GenOpt can be setup to work
with TRNSYS without too much difficulty, and TESS has developed a
front-end called TRNOpt if you want a mor user-friendly solution.
Kind regards,
Michaël Kummert
