Hello everybody..

I'm modeling a wind turbine in CFX.I'm using two different domains( one rotary cylindrical domain around the blades and one bigger Stationary domain around that rotary domain.)
I check my blade model in that inner rotary domain individually for a lot of different air velocities, and for all cases it is ok. Number of nodes for this domain is 3.1 Million and the quality of this domain is about 40%.

Also my surrounding domain, outer big stationary domain, contains about 1 million nodes and is in high quality( 60%).

Now my problem is that although both domains are good and I have good results when I use single domain but, when I import them and combine them as two Domains at the same time I have the following error:

--------------------------------------------------------------
ERROR #001100279 has occurred in subroutine ErrAction
Message:
Incompatible sparsity patterns

---------------------------------------------------------------

Does anybody know how to solve this error and what 's the source of this error?
