RE: Failure criteria?
i am working with DEBOND two surfaces, my file get this kind of massage: "THE SLAVE-MASTER PAIR ASSEMBLY_DB2 ASSEMBLY_DB1 SPECIFIED ON *DEBOND HAS NOT BEEN DEFINED. THIS MAY BE DUE TO NONEXISTENT SLAVE OR MASTER SURFACE, OR DUE TO ERRORS WHEN PROCESSING THE *CONTACT PAIR KEYWORD". Althought i have already defined it in CONTACT PAIR and again in INITIAL CONDITIONS. Please help me how to solve this problem.
Thanks
