a number of particular parameters. Is there any capability implemented in
TRNSYS, which could help to develop this kind of

Beatriz,
There isn't a built-in sensitivity analysis inside of standard TRNSYS,
but you could use the parametric table option inside of TRNSHELL to
perform an entire series of runs (varying multiple parameters) and then
perform your analysis in a post-processing program such as Excel.
The other option that comes to mind is our TRNOPT program which performs
a multi-variable optimization on a TRNSYS input for a range of discrete
and continuous parameter values. If you used this approach you'd
have to come up with a clever method of formulating the sensitivity
analysis as an error function.
