Couple error
 
I have just run the analysis and it has come up with the following error:

CHECK ALL COUPLES A NEW CPSET WILL BE FORMED FROM ALL FAILED COUPLES **ERROR - SLAVE CELL 7425 FACE 5 OF COUPLE 111

IS A MASTER IN COUPLE 69 **ERROR - MASTER CELL 9285 FACE 5 OF COUPLE 112

IS A SLAVE IN COUPLE 69

**SUMMARY OF CORRECTLY MATCHED AREAS**

TOTAL MASTER FACE AREA = 3.4938580

TOTAL SLAVE FACE AREA = 3.4995410

TOTAL AREA OF OVERLAP = 3.4892430

COUPLE CHECK COMPLETED. 2 ERRORS FOUND. NUMBER OF COUPLES PLACED IN COUPLE SET = 3

Can anyone tell me how to resolve this please?

Thanks

Regards

Put couples check, and keep the option of create failed couples set on. After getting the couple error, try for couple merge. Again re-check

Most likely it will work. such messages come with multiple couples assigned to one or more cells face.

Re: Couple error
 
When I do that one of the errors disappear, but one still remains:

cpmerge,all BEGINNING SEARCH FOR DUPLICATED COUPLES

**NOTE - COUPLES 112 AND 69 BOTH HAVE CELLS:

9285 7425

COUPLE 112 WILL BE DELETED

1 DUPLICATE COUPLES FOUND CHECK COMPLETED

MESH*> cpcheck,0.01,all,,,,0.05,nofix CHECK ALL COUPLES **ERROR - SLAVE CELL 7425 FACE 5 OF COUPLE 111

IS A MASTER IN COUPLE 69

**SUMMARY OF CORRECTLY MATCHED AREAS**

TOTAL MASTER FACE AREA = 3.4938580

TOTAL SLAVE FACE AREA = 3.4995410

TOTAL AREA OF OVERLAP = 3.4892430

COUPLE CHECK COMPLETED. 1 ERRORS FOUND.

And I can't seem to get rid of this one, please help.

Thanks

Re: Couple error
 
If one problem is still there after couple merging. Means some local coupling problem is there.

Locally you should see the corresponding cells/coupling faces, keeping in mind the coupling rules. To start with, after checking for couples, delete the 1 couple which is giving problem and check for cracks locally.
