Element DISCRET 3D, 4 models:
modeling DIS_T: T_L (mesh SEG2)
modeling DIS_T: T_N (mesh POI)
modeling DIS_TR: TR_L (mesh SEG2)
modeling DIS_TR: TR_N (mesh POI)
Modeling DIS_T: T_L (\(\mathrm{AB}\): mesh SEG2)
Zero displacement in \(A\): \(\mathrm{DX}=\mathrm{DY}=\mathrm{DZ}=0\)
Strength in \(B\): \(\mathrm{FY}=-1000N\)
Modeling DIS_T: T_N (mesh POI)
Zero rotations in \(A\): \(\mathrm{DRX}=\mathrm{DRY}=\mathrm{DRZ}=0\)
Strength in \(B\): \(\mathrm{FY}=-1000N\)
The mesh of this modeling is composed of a mesh POI (point \(A\)) for the discrete element (T_N) and a mesh SEG2 (\(\mathrm{AB}\)) for the beam element.
