Modeling D_ PLAN_HHMS

3.2. Characteristics of the mesh#

  • Number of knots: 981

  • Number of meshes: 80 of type SEG3 and 300 of type QUAD8

The following post-processing nodes are defined:

  • \(\mathit{NBASE}\): at the base of the right edge

  • \(\mathit{NTROU}\): in the middle of the opening

  • \(\mathit{NSUP}\): at the top of the right edge

The travel limit conditions imposed are:

  • On side \(\mathit{BAS}\): \(\mathit{DY}=0\) and \(\mathit{PRE}2=0\)

  • On sides \(\mathit{GAUCHE}\) and \(\mathit{DROIT}\): \(\mathit{DX}=0\) and \(\mathit{PRE}2=0\)

  • On side \(\mathit{HAUT}\): \(\mathit{PRE}1=0\)
