How to correct error 84, master cell face in one couple is defined as a slave cell face in another couple. Thank you

Delete the couple and redo the coupling with proper master and slave cells defined.

Thank you, But I can't do it. Please tell me more detail.

You can control which cell is used as a master and which one as a slave by assigning different cell types. Use the couple tool for creating, checking, deleting couples.

hi tipakorn

try with this option

in prostar - tools - couple tools go for couple check - use YES option at remove non overlapping slaves

this may help you ..all the best anand

Thank you I used to do this but there are errors.

It may be that the chunck of cells in question are just badly formed. Cut out the cancer and put something better in - make new cells and cpmatches.
