[TRNSYS-users] TRNFLOW convergence problems

[hotline]

Dear Francisco,
 
in general you don't need to change the parameters.
Convergence problems are often introduced by the control of openings.
You may check you settings.
Also have in mind that if you open a large opening often high air flows
occur.
You may try to open it step by step.

Betreff: [TRNSYS-users] TRNFLOW convergence problems




Dear all, 

I am working on a rather simple trnflow simulation, and having
convergence problems even at very low timesteps and high tolerances (in
the simulation control cards). When I turn off trnflow everything is OK.

Is there anything I can do about this? Should I try and modify these
parameters in the type56a-Trnflow parameter list as well? 

Thanks in advance,
