Refinement and boundary problems
After mesh refinement I have problems with cyclic boundaries matching. I've tried to redefine these boundaries and to match them from the start, but it doesn't work. I keep receiving error messeges about duplicate master cells or not-matched cyclic boundaries.

Re: Refinement and boundary problems
Hi Julie,
Perhaps you can select, delete and compress the cyclic boundaries, then use "count boun" to verify the're gone. Next go to the cyclic sets list, and show, delete and compress all cyclic sets. Then redefine everything. Sometimes (for extreme refinements, or when the regions to be matched are very far apart in Prostar units) the geometric accuracy of Prostar is insufficient, and no(t all) matches can be found. Usually increasing matching tolerance solves this problem (or incorrect matches are created (-;), Cheers, Jasper. |

Jasper, Thank you for the help. Just one more stupid qestion: What a difference between the cyclic set and the cyclic boundary?

Re: Refinement and boundary problems
A cyclic boundary is the 2-dimensional region on your geometry you designate as such.
The connections you specify between the cell faces of your cyclic boundaries are termed cyclic sets. You will find is all on pages 7-35 / 7-40 of the star user-guide, Cheers, Jasper. |

Thank you, Jasper!
