Hello,

I am currently simulating a solar hot water system using two serial
storage tanks. It seems to be pretty difficult to get a stable system
and most simulation runs are stopped due to convergence problems.

Could anybody give some general hints on how to handle convergence
problems with type 60?

Does problems due to the already discussed bug in type 60 (negative UA
at the heat exchangers) occur frequently? Are they common or is it not
easy to reproduce them? Is this bug beeing fixed for TRNSYS 16?

Thanks for your help!


Timo
