Hello, I have APDL contact macro. I want to implement the contact on Ansys Workbench.

Element Type 171 is a Legacy Element. Although this element is available for use in your analysis, ANSYS, Inc. recommends using the more general purpose CONTA172 element which can be used with or without midside nodes.

CONTA172 is for 2D analysis.  In Workbench, create your geometry on the XY plane then in Mechanical, under the Connections folder, Insert Manual Contact Region. select the Target edges and the Contact edges.  There are many other steps in Workbench and Mechanical to setup a 2D analysis. Search this site for examples.

You used Keyop(9) = 1 which says to ignore initial Gaps or Penetrations.  You do that in Mechanical under the Details of the Contact, in Geometric Modification, set Interface Treatment to Adjust to Touch.

Thank you for answer, but result is already false. In ANSYS APDL I have different result with Workbench. Also my APDL result is compatible with experiments.

I'm searching solution. Anyone knows it?
