5. C modeling#

5.1. Characteristics of modeling#

The modeling tested is DIS_T on a SEG2 mesh. The stiffness characteristic of the discrete is of the K_T_D_L type.

5.2. Characteristics of the mesh#

Number of knots: 2, number of stitches: 1, Elements SEG2: 1.

5.3. Boundary conditions and loads#

The on-the-go condition is set to \({U}_{0}=0.1m\).

5.4. Discretization in time#

The analysis time step and time interval are:

\(\Delta t=\mathrm{4,0}{10}^{-3}s\) and \(t\in [0s\mathrm{,1}s]\)

5.5. Tested sizes and results#

The quantities tested are the effort and the dissipation for a loading duration of \(1\mathit{sec}\). The equations and are evaluated in the test case. Tolerances are by default.
