[EnergyPlus_Support] problem with air network

[kostas ordoumpozanis <ordoumpozanis@xxxxxxxxx>]

Hi,
I am trying to simulate a complex building with  a AirflowNetwork to calculate the ventilation due to an attrium.

when I am trying to run this AirflowNetwork I get this error
** Severe ** Too many iterations (SOLVZP) in Airflow Network simulation
** Warning ** AirflowNetwork: SOLVER, Changing values for initialization flag, Relative airflow convergence, Absolute airflow convergence, Convergence acceleration limit or Maximum Iteration Number may solve the problem.

any help with this ???

Thanks
