We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

  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
