3. Modeling A#
3.1. Characteristics of modeling#
We use a MEMBRANE modeling in large deformations (DEFORMATION =” GROT_GDEP “) with the Saint Venant Kirchhoff law of behavior (RELATION =” ELAS_MEMBRANE_SV”). Linear elements are used.
3.2. Characteristics of the mesh#
The mesh contains 132 elements of type QUAD4.
3.3. Tested sizes and results#
The displacement at the center of the membrane subjected to gravity, in O, with respect to the semi-analytical solution is tested.

3.4. notes#
We used linear research (RECH_LINEAIRE) to achieve convergence.
