Element DISCRET 2D, 4 models:

• 2D modelling_ DIS_T: T_L (mesh SEG2)

• 2D_ modeling DIS_T: T_N (mesh POI)

• 2D modeling_ DIS_TR: TR_L (mesh SEG2)

• 2D modeling_ DIS_TR: TR_N (mesh POI)

2D Modeling_ DIS_T: T_L

• Zero displacement in :math:`A`: :math:`\mathrm{DX}=\mathrm{DY}=0`

• Strength in :math:`B`: :math:`\mathrm{FX}=-1000N`, :math:`\mathrm{FY}=-1100N`

2D Modeling_ DIS_T: T_N

• Strength in :math:`B`: :math:`\mathrm{FX}=-1000N`

The mesh of this modeling is composed of a mesh POI (point :math:`A`) for the discrete element (T_N) and a mesh SEG2 (:math:`\mathrm{AB}`) for the discrete element (T_L).

2D Modeling_ DIS_TR: TR_L

• Zero displacement in :math:`A`: :math:`\mathrm{DX}=\mathrm{DY}=\mathrm{DRZ}=0`

• Strength in :math:`B`: :math:`\mathrm{FX}=-1000N`, :math:`\mathrm{FY}=-1100N`

2D Modeling_ DIS_TR: T_N

• Strength in :math:`B`: :math:`\mathrm{FX}=-1000N`

The mesh of this modeling is composed of a mesh POI (point :math:`A`) for the discrete element (TR_N) and a mesh SEG2 (:math:`\mathrm{AB}`) for the discrete element (TR_L).
