3. Modeling A#
3.1. Characteristics of modeling#
We calculate the mean deformation from a static response calculation with MECA_STATIQUE.
The operator OBSERVATION is also used for the surveys of displacement fields and deformation.
3.2. Characteristics of the mesh#
Knots: 1029
Meshes: 720 HEXA8
3.3. Tested sizes and results#
The deformation value is tested at the nodes in the middle of the beam.
