Re: [EnergyPlus_Support] Re: Airflow Network



Yes, I increased the number of iterations up to 30000 and convergence limit to 500. It is showing the same error.

The default value for number of iterations is 500.  Have you tried increasing this or adjusting the convergence criteria?

Hi Bruno Scalet,
 
Thanks again.
 
I tried with INPUT option. But still it is giving the same error. Any further suggestion.

Hello,
 
I had the same problem today. As written in the I/O file, the AirflowNetwork object with "SurfaceAvarageCalculation" option in the field "Wind Pressure Coefficient Type" only supports simple geometry (rectangular or squared ones). If your geometry/envelope is different from it you should use the option "Input" which will require all the pressure entries to this building you are modeling.
 
I hope I've helped you.
 
Greetings,
 
Bruno Scalet
