suggestion: CFD for large plant
 

Hi readers,

please suggest me regarding the use of CFD for a plant ,air conditioning system for area around 350m x 100 m , which is very huge for the solver to solve and to get me the results.
Can it be solved???
can i solve a small part of it and than attach the other area with same results in post.
What probably is the best solution for solving susch a big area using CFX 11.0. ??

Please help !!!!
