Dears,
Could anyone can tell me why trnflow solver has the problem of the convergence when the building zone heating type has a high radiative part, please?
For example, I have a one-zone building with
- a heating type of 9000 kJ/h and radiative part of 0.9, the zone temperature is set at 20 °C
CR_001 DS_001
- trnflow network with EN_01
à ZONE_01
à EN_02
For launching the simulation, I had the problem with internal convergence of trnflow:
Convergence of the internal iteration of TYPE 56 not attained within 100max. number of internal iteration.
When I decrease the radiative part of heating type to 0.8 the simulation work well without any error.
Any help will be appreciated!
Thank you very much.
Long
