It does not seem to be systematic apart from the zone's thermal capacitance which always gets set back to its default value during the process. When I export a *.b18 to an *.idf, make changes, and then reimport back to a *.b18 I usually take a look at the before and after versions of the *.b18 using a text compare tool (I use CompareIt but there are many others). <o:p></o:p></p><p> In your file it looks like a new HEATING type got added (HEAT002) and that the heating in zone "parter" got changed from HEAT001 to HEAT002. The set point temperature for HEAT001 and HEAT002 are the same though so I would have expected the behavior to be the same before and after the changes that you made in the *.idf. <o:p></o:p></p><p>The other change I notice is in the windows; two unused WINDOW types were removed and one new one was added.<o:p></o:p></p><p>I'm not sure that any of the above will help but I hope it does!<o:p></o:p></p><p>best,<o:p></o:p></p><p> David<o:p></o:p></p><p><o:p> </o:p></p><div><p class=MsoNormal>On 05/20/2021 04:17, Karol BANDURSKI via TRNSYS-users wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal>Dear Experts,<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>I have problem with my b18 file (I use demo version).<o:p></o:p></p><p class=MsoNormal>The first model consist of 2 floors connected partially by Virtual Surface and partially by visible surface.
