Dear TRNSYS users, I am trying to gauge the interest of an optimisation tool for TRNSYS in this group. I have heard about TRNOPT and MULTIOPT, though never seen them in action myself. So the first question is, is there any need for another tool for the same purpose? jEPlus (www.jeplus.org) has implemented support for TRNSYS parametrics since version 1.4. The latest development has added the RVX file to TRNSYS projects, so that sophisticated result collection and post processing (inc. using Python script) can be specified, along with the definition of penalty and fitness functions. This enabled TRNSYS projects to work with jEPlus+EA, the EA-based multi-objective optimisation package (see http://www.jeplus.org/wiki/doku.php?id=docs:jeplus_ea:start). The basic mechanism is working. However, since I am not a TRNSYS user, the next stage of development will require your help. So my next question is, is here anyone who is willing to help with this development? What you need to do is essentially test driving the tool with a realistic problem, and tell me what works and what doesn't. As a return, you will get the tool for free always. Please get in touch if you are interested! Best regards, Yi Dr Yi Zhang, PhD CEng MCIBSE MASHRAE Director Energy Simulation Solutions Ltd. (UK) T: +44 (0)7809 572863 |
