The question about mixasi
 

Hi, I have some quastion. When using rotating meshes in star-cd 3.15 I try to write geometry file before and after using procedure MIXASI (see tutorial 7.3 or like this). In output window I obtain the difference:

before

PROCESSING PARTIAL BOUNDARY TRIMMED CELLS.

BEGINNING PROCESSING OF TRIMMED CELL COUPLES. 2934 PARTIAL BOUNDARIES TO PROCESS.

2000 PARTIAL BOUNDARIES PROCESSED

BEGINNING SEARCH FOR INTERNAL CUTS. 377849 CELLS TO SEARCH.

18000 CELLS SORTED

36000 CELLS SORTED .... 360000 CELLS SORTED

SECOND PASS COMPLETE - 377849 FLUID CELLS FOUND CONNECTIVITY COMPLETED

317 TRUE PARTIAL BOUNDARIES FOUND

2617 TRIMMED PARTIAL BOUNDARIES FOUND

after

PROCESSING PARTIAL BOUNDARY TRIMMED CELLS.

BEGINNING PROCESSING OF TRIMMED CELL COUPLES. 395 PARTIAL BOUNDARIES TO PROCESS.

BEGINNING SEARCH FOR INTERNAL CUTS. 377849 CELLS TO SEARCH.

18000 CELLS SORTED

36000 CELLS SORTED .... 360000 CELLS SORTED

SECOND PASS COMPLETE - 377849 FLUID CELLS FOUND CONNECTIVITY COMPLETED

317 TRUE PARTIAL BOUNDARIES FOUND

78 TRIMMED PARTIAL BOUNDARIES FOUND

this change leads to error when solvong problem (like this: cell 1 connects to cell 2 face 3 which is boundary/cut). Moreover MIXASI produces this change only into rotating part of mesh. Can anybody tell, how MIXASI cganges geometry and how can one avoid the problem? Thanks.
