Dear all, I would like to give a little advice on the use of type 2 (controller) with type 60 (storage tank). The new version of type 2 is supposed to be solved using Powell's method, however, up to me, the simulation is not working properly due to convergence problems (also bringing plenty of time). On the other hand using the old version of type 2 would remove that unwanted behaviour. I hope this comment could help. cordially, Lorenzo -- |||||||||||||||||||||||||||||||||||||||||||| Lorenzo Zamboni - Ing - PhD - UNIVERSITA' DI PADOVA Dipartimento di Tecnica e Gestione dei sistemi industriali [DTG] UNIVERSITY OF PADOVA Department of industrial management and engineering stradella S.Nicola, 3 36100 VICENZA - ITALY phone: +39 0444 99 87 78 mobile: +39 349 73 06 450 e-mail: lorenzo.zamboni@gmail.com lorenzo.zamboni@katamail.com |||||||||||||||||||||||||||||||||||||||||||| |
