[TRNSYS-users] TRNSYS18 cannot properly read the TRNSYS17 files?

Mon Jul 8 08:09:44 PDT 2019

Siliang,

   This sounds like an issue that should be sent to your TRNSYS 
distributor for tech support. Trnsys18's TRNBuild should be able to 
correctly read and interpret Trnsys17 building description files. If you 
aren't sure who to contact, please send me a direct email and I can 
point you in the right direction.

kind regards,

  David
