+Derivations of Traction2DElement and Traction3DElement with the possibility to set the traction/shear force of a node to zero, when this node is in contact within a specified contact interaction.  To determine the contact status, the contact flag of the previous time step is used.
 === Parameters ===
+The same than in Traction2DElement and Traction3DElement, with the following additional parameter:
