Re: [TRNSYS-users] digging into trnflow convergence problems



Maybe you have already tried it, but you can make your simulation time step smaller (in steps of 1/(2^n))

 

Kind regards,

Dear all:

I am working on a trnflow simulation (an apartment with passive stack exhausts), and having some convergence problems. After looking at it I have found these problems occur whenever the outside temperature gets significantly higher than the interior temperature, as you can see in the attached image. Any suggestion on how to deal with this?

Thanks,
