Hi, Thank you very much for Lee's information. I have contacted our TRNSYS distributor as well as the contact person of the non-standard Type TRNSYS-SBM. We currently get the information that TRNSYS-SBM is only available for TRNSYS 15. And if we want to upgrade it to TRNSYS 17, it seems that we need to do some Fortron programming work. Is there anybody has the experience to use TRNSYS-SBM in TRNSYS 17? Is it very difficult to upgrade TRNYSYS-SBM so that it can be compatible with TRNSYS 17? From some references, we also know that sometimes it might be very time-consuming to simulate with TRNSYS-SBM. Is there anybody has the experience of simulating a large scale ground source heat pump system with TRNSYS-SBM? How slow it might be (I know it depends, but just want to know some examples)? As the price for TRNSYS-SBM is not very cheap (and there is no demo version for that type), I just want to make sure it CAN be effectively used in TR! NSYS 17. Thank you very much.
