[TRNSYS-users] TRNSYS crashes with no error message, but a lot of warnings refering to the PSYCHROMETRICS routine

[David BRADLEY]

Knut,

   In migrating to 64-bit architecture we have run into some situations 
where the 32-bit version managed to get through an iteration while the 
64-bit version doesn't. Can you please send me the project and all the 
files needed in order to run it so that I can have a look where it is 
getting hung up?

thank you,

  David
