Is it possible to import optimization subroutine developed in fortran to
ISSiBAT envionment like other user modeled subroutines. Or otherwise, is
there any modules available for optimization in TRNSYS, if so from where
to get one. Please help.
Perfect timing on this question as we have just finished readying TRNOPT
for Version 16 of TRNSYS. TRNOPT is an interface program that allows
TRNSYS users to quickly and easily utilize the GENOPT optimization tool to
optimize combinations of continuous and discrete variables. GenOpt is a
powerful optimization algorithm written by LBNL that we have used
successfully for the past couple of years in our studies. However, getting
it to work properly with TRNSYS can be pretty tricky. We're written TRNOPT
to overcome this barrier. TRNOPT scans your TRNSYS input file (either
outside of or from within the new Simulation Studio (IISiBat) using the new
PlugIn feature) and allows uses to choose TRNSYS variables to be used in
the optimization process. The user specifies the initial guess for the
variables, the range of the variables, the optimization method, and the
error function (either a TRNSYS equation or output from a component). The
TRNOPT program then creates the required template and configuration files,
calls GenOpt and the optimization process is begun. I've attached a few
screen captures from the program and from the included example.
TRNOPT is available from TESS as an add-on library for TRNSYS 16; we now
have 12 of these libraries of component models with complete technical
documentation available. Some information on our libraries may be found on
the TRNSYS.com web site. Otherwise we can send you a PDF document
describing each of the libraries and the models they contain.
With kindest regards,
Jeff
