Cyclic Reference Problem

Hi,
I am trying to analyne a building (see attached file). I have reached upto 4th floor without any problem. But when I add more floors, I cannot analyze the building anymore. When I click on calculate button, it shows the following error message - "model error - a cyclic reference in the definition of kinematic constraints ..."
Why is this happening? From the 3rd floor all the floors above are identical, so I am using the translate option. So if upto 3rd floor is correct, then the rest should be correct also. But it still shows error.
However I tried to change the meshing to 0.5 meters. It works, but it makes the file very large. When I complete upto 18th floor, it generates almost 130000 nodes and it takes almost 30 minutes to calculate.
How can I solve this problem?
Solved! Go to Solution.

Thanks a lot! I also solved it yesterday by complex meshing, but there was 32000 nodes.

If you look at my screen shot settings of greyed out fields are also important
