Hello.

I want to study the affect of the wake from the incoming wind from the first wind turbine tower to the second.
In boundary conditions, i use one domain, an enclosure box that has the two geometries. However, i have this  problem in Solver and i cant run the modeling.

 2 isolated fluid regions were found in domain Default Domain

 
 If the isolated regions do not have the pressure level set either

 by the boundary conditions or using a reference pressure equation,

 you may encounter severe robustness problems.

  
This situation may have arisen because a domain interface was not

 properly defined during problem setup.  Please carefully check

 the setup.

  
 The solver will stop now and write a results file.  The isolated

 regions can be visualised in CFX Post by making plots of the 

 variable "Isolated Volumes".

  
 If you are sure that the pressure level is set in each isolated

 fluid region then you can force the solver to turn off this check

 by setting the expert parameter "check isolated regions = f".

 

 Can you help me ? Is it connected with interface someway ? 
The simulation is with ANSYS-CFX Academic Version

Thanks

Sounds like you've not got connected geometry: how did you split out the turbine volumes?

I considered to take them as part body with the 2 two turbines as solid parts. 
I have also one enclosure (a box) that includes the above. 
In CFX-Pre i insert the conditions in one domain. 

I can send the file as archive if you want to have a look. 

Thank you !

Please post an image of section through the mesh through the outer domain and a turbine. We're not permitted to open/download files so images in with the text please.
