Hello,
I am modeling compressor stage and using a fairly standard process in ICEM CFD 15.0. Geometry clean up --> surface mesh using octree-->Delaunay for vol --> mesh inspection and merging/moving nodes as per need --> make consistent and flood fill --> check mesh --> prism layer. In my earlier models this approach worked just fine. I am doing mesh independence study now and this problem has surfaced. I get below pasted errors and then i can't export the mesh in CFX (gives the error: not able to generate the valid mesh elements). cells near -0.029893 -0.019099 -0.024232 occupy the same volume cells 15692 and 44060 face node numbers 2306856 8236784 8615586 opposite vertices 4114464 4114464 cells near -0.038707 -0.022714 0.013155 occupy the same volume cells 1245012 and 3603 face node numbers 7702011 7702012 8226339 opposite vertices 7702010 1437046 cells near -0.038904 -0.022690 0.013163 occupy the same volume cells 3603 and 4871369 face node numbers 1437046 7702011 7702012 opposite vertices 8226340 7702010 cells near -0.038904 -0.022690 0.013163 occupy the same volume cells 3603 and 99903 face node numbers 1437046 7702011 8226339 opposite vertices 7702012 8226340 cells near -0.038904 -0.022690 0.013163 occupy the same volume cells 81795 and 3603 face node numbers 1437046 7702012 8226340 opposite vertices 2761432 8226339 cells near -0.038904 -0.022690 0.013163 occupy the same volume cells 3603 and 99903 face node numbers 1437046 8226339 8226340 opposite vertices 7702011 7702011 cells near -0.029957 -0.018940 -0.024029 occupy the same volume cells 50299 and 15692 face node numbers 2149332 2306856 4114464 opposite vertices 8615586 8615586 cells near -0.029957 -0.018940 -0.024029 occupy the same volume 22 more messages - not printed All messages saved to file ERROR_LOG6.tmp" Before generating the prims, default check mesh shows no errors (except multiple edges, which are intended in model). I was wondering if anyone could share inputs on what might be wrong with model. How can i see these element number mentioned in the error log in ICEM screen and also if i could get any pointers on the direction to mitigate this situation would be highly appreciated. Thank you and I look forward to response. |
