Modeling A ============== Characteristics of modeling ----------------------------------- The modeling is 3D for the concrete ring and BARRE for the cable. The cable is of type PASSIF/ACTIF: PASSIF to the group of nodes ANCR1 and ACTIF to the group of nodes ANCR2. The linear friction BPEL is taken to be equal to :math:`\mathrm{0,01}` and the curved friction to :math:`\mathrm{0,03}`. In a first phase, the cable is prestressed with CALC_PRECONT and a tension of :math:`{10}^{6}N` and without anchor recoil. In a second phase, a :math:`\mathit{DY}=-\mathrm{0,1}` move is imposed on the group of nodes ANCR2. Characteristics of the mesh ---------------------------- The mesh contains :math:`20` elements of type HEXA8 and 20 elements of type SEG2. Tested sizes and results ------------------------------ The results tested are of the non-regression type to serve as a reference in the B modeling and concern the displacements and the tension in the cable (see values in ยง :ref:`4.3 `).
