Error in domain creation
 

hi all,
I am unable to create an unstructured domain in pointwise via assemble special. can anyone suggest me what may be the problem?
In the figure after choosing the 2nd connector, I cannot choose the next connector(clockwise) which is in the XY plane.

Mainly I want to create a block around my aerofoil(around which I have already generated the inflation layer and created an aerofoil block) in my confined computational domain. Now after creating these two periodic surfaces when I chose to create an unstructured block it was saying some no. of connectors and domain were unused and the block was not created, Hence now I am trying to create separate surfaces(6) and then use assemble special to create a block.


Thanks in advance.

Zoom in at the corner where the selection stops. You may have nodes that are not properly connected (merged).

Can you attach the PW file?
