Ansys workbench: contact

[choupiced]

Hello,

If I delete a contact area, is Ansys considered that there was no contact between the two sides during simulation?

Thanks.

Hi,
implicitly yes, if I understand your point correctly, since Ansys will allow the area to be deleted ONLY if the mesh on it has been cleared, thus deleting the contact elements. But in this case, you destroy your mesh and can not reactivate this contact later in the analysis. If, instead, at some step you unselect the elements belonging to the contact pair, you achieve the same result while still having your elements stored. In this case, make sure the contact pair's properties are such as to allow the contact stiffness calculation at every loadstep (or, better, at each equilibrium iteration).
