Re: DID NOT CONVERGE in FUNCTION THP

[Michaël Kummert <kummert@xxxxxxxxxxxxx>]

Dear Louis,
If I am right, you are getting those errors using the STEC library. I 
think the error occurs in the "steam3" routine, which calculates steam 
properties. Sometimes, errors in properties calculation routines happen 
because you are outside of their intended range due to some problems in 
your project (bad connections, wrong initial values, typo in parameters, 
etc.). You could try starting from a simple configuration that works and 
add components progressively to find out what causes your problem.

If your problem persists, you should contact the STEC library developers.

Regards,

Michaël Kummert

PS. As you say, the "Type 3" warning is not related to "TRNSYS Type 3", 
I think it is just a third Type of something in the "steam3" routine.
