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
