Hi,

Depending on your problem definition WB is going to "automatically" choose the "best" contact element based on several parameters. You can use the advanced option to choose between augmented lagrange, MPC, etc which will affect the element contact type.

But in order to have full control you need to add a command snippet under the contact and change the contact type using the APDL command:

et,cid,176 !change element type to 176 -> change it to the contact element reference you need

Have fun
