3. Modeling A#
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: |
94 elements QUAD8 |
3.3. Tested sizes and results#
The parameters of the result data structure are tested:

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