roto-translational Periodic BC in CFX
 
Hello,

I would like to simulate fully developed conditions in helical tubes with CFX10. Describing an entire pitch (2*pi), I can impose periodic boundary conditions (INLET-OUTLET) with a 'Periodicity Type'='Translational'. This works well. But I would like to simulate only small portion of the tube; in this case the correct periodicity should be 'rotational' and 'translational', i.e. roto-translational. Does anybody know how to impose this condition in CFX10?

Thank you in advance, Ivan
