3.1. Characteristics of modeling#

Loading and boundary conditions are modelled by:

DDL_IMPO: (GROUP_NO: NOEHGFE, DY: 0.)

LIAISON_DDL :( NOEUD :( N1 NXXX), DDL :( 'DY', 'DY'), COEF_MULT :( 1, -1), COEF_IMPO :0.)

for all nodes belonging to edge \(\mathrm{AD}\) (\({u}_{z}\) uniform on \(\mathrm{ad}\))

PRES_REP: (GROUP_MA: AH, PRES: p (t))

where \(p(t)\) is the positive function defined précédemment.

3.2. Characteristics of the mesh#

Number of nodes:

381

Number of meshes and types:

3.4. notes#

We stopped at \(t=60s\) so as not to have too long a calculation time.
