 +==== ContactTraction2DElement, ContactTraction3DElement ====
 +
 +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 parameters:
 +
 +^  Name  ^  Description  ^  Dependency  ^
 +| ''NUM_CONTACT_INTERACTION'' | Number of the contact interaction, which is tested for the contact status |  -  |
 +| ''TRACTION_AT_TRANSITION_ON'' | If True (default), the traction of a node belonging to an element at the transition from contact to no contact is not set equal to zero, although the node is in contact  |  -  |
