  3. When using “Add offset no ramped effects” in contact geometry correction, how can I solve the interference fit in terms of function? i.e., instead of adjusting the contact surface to a fixed value, I would like to gradually adjust it as a function of a coordinate value (say X for example).

      Contact surface offset is real constant #10. It can be defined as a tabular function of certain primary variables including TIME. Please refer to Section 3.9.1.2 of Contact Technology Guide for more details. https://ansysproducthelpqa.win.ansys.com/account/secured?returnurl=/Views/Secured/corp/v191/ans_ctec/Hlp_ctec_realkey.html%23ctecrealtabular The main aspects of the attached example include: 1. The use of a local coordinate system. 2. Use of a command snippet, which creates a table and includes the offset values based on the x values. 3. Modification of the real constant 10 using the Contact ID (cid). *dim,xoffset,table,6,,,x,,,12 ! create a table parameter called xoffset xoffset(1,0)= 0,5,10,15,20,21.42 ! these are the x values xoffset(1,1)= 0,0.374,0.748,1.122,1.496,1.87 ! these are the offset values rmodif,cid,10,%xoffset% ! use the table for OFFSET real contant of realID of cid
