Hello TRNSYS users,

I'm trying to model Phase-Change Materials in TRNSYS with Type 204.
However, the example downloaded does not even work since I get the error
:"forrtl: severe (29): file not found: unit 51: [filepath]". What is
fort.51 file? fort. seems to be temporary files created by TRNSYS
itself...am* *I correct?
By checking online, I understand that Type 204 can be troublesome but it
seems it actually runs most of the time!
Does it ever happen to someone?

Thank you for your help,
Best regards,
