In this contribution an isogeometric contact treatment by the penalty method is presented. The symmetry preserving formulation, also known as the two-half-pass formulation, is utilized together with the Gauss-point-to-segment discretization. A particular attention is payed to the contact detection, i. e. to the closest point projection of a point onto a NURBS patch. The problem of contact pressure post-processing is also presented in more detail.
