Hello, the SBM is not a standard type. You may ask at TRANSSOLAR (http://www.transsolar.de/) if it is available. Transsolar is the German Trnsys distributor. You also may ask Mr. Hellström (http://www.matfys.lth.se/Goran.Hellstrom/), who is one of the developers of the SBM. Sincerely, Janet Nußbicker-Lux *************************** Universität Stuttgart Institut für Thermodynamik und Wärmetechnik |
