DOMAIN error

["Ulrika" <Ulrika.Ottosson@xxxxxxxxxx>]

Dear everybody!

Can someone help me trouble shoot? I'm trying to simulate a small
district heating system, with the simulation running for a year. The
site is Umeå. Everything works fine until end of May, when the heating
need gets low. I then receive the message that there is a floating point
error, the simulation is terminated and I get the following message;

Run-time error M6201: MATH -log: DOMAIN error

Followed by a list of Images (TRNLIB.DLL, Trnsys.exe, kernel32.dll),
with various PC-numbers, routine, line and source unknown.

None of this makes much sence to me. I would really appreciate some
ideas on how to find the problem and fix it!

Kind regards,

Ulrika Ottosson
