[esp-r] warning messages from networks during simulation

[Nuno Fernandes]

Dear all esp-r users

 

I have a question related with fluid flow networks.

 

In my project I have a big zone that I have sub-divided. The contact
surfaces between this zones (sub-divided) were set as transparent fictitious
constructions.

 

Them I have set an all air fluid flow networks between them and define the
components between the interior nodes as openings corresponding to all the
contact area between the zones.

 

However when I rum the simulator a warning message appears:

 

Please check (in the following order) that:

-          each node has some flow path to a boundary pressure and

-          iteraction convergence control is not to strict.

Day 23 Month 12 Hour 13.00 : 100 iteractions: flows solution failed 

 

 

This happens for several days months and hours.

 

Can someone explain me watts’ wrong.

 

Thanks in advance.

 

 

Best regards,

 

Nuno Fernandes
