<br><font size=2 face="sans-serif">Dear Marion,</font>
<br>
<br><font size=2 face="sans-serif">many thanks for your answer. You are
right, this morning I run a shorter simulation and saw the problem was
related to a sudden increase of airflow caused by a window opening schedule.
I run another simulation with closed windows and it converged, but I realised
I have no flow from infiltration. I thought this was provided by the "for
closed opening" parameters in the Large Opening Type Manager. Any
suggestion about that?</font>
<br>
<br><font size=2 face="sans-serif">Also, I modified my window schedule
by increasing by 0.02 the opening factor each minute and using a short
(0.0125) timestep. My simulation does not stop, but I still get some convergence
problems, probably due to very large flows in the kitchen, which also has
stack ventilation... Could some unrealistick stack parameter be the
cause?</font>
<br>
