[TRNSYS-users] Urgent!! - help on Type 340 Multiport Storage

[Janne Paavilainen]

This is an "old" trick:
Increase Type340 parameter 123 " precision for the mixing process in the store" to a large value. 

This shouldn't affect results much, but that should be of help to the simulation getting stuck. And might also make it run a bit faster. 
Try 5 or 10 even 100 or something even larger. Also compare the results with the different values for this parameter to see if you get significant differences.

Subject: [TRNSYS-users] Urgent!! - help on Type 340 Multiport Storage

Hello everybody,

currently I have a problem with Type 340. I use it on system with
 different heat sources. Heat exchanger 1 is a solar loop, Heat
 exchanger 2 is warm water supply. 2 Doubleports are used for heating
 purpose.
Unfortuanately the system is very unstable. Sometimes it works,
 sometimes it hangs up without any warning or message.
Has anybody made the same experience?
Any suggestions?

I am sure that I defined every parameter right. So the problem depends
 on the simulation system...

Thanks, 

S. Thiemann
