3. Modeling A#

3.1. Characteristics of modeling#

We use a:

  • 3D modeling and POU_D_E for the beam,

  • A DIS_TRde element type POIau point C,

  • 3D connection_ POUau point ATo connect the beam and the volume face,

  • 3D connection_ POUau point C to connect the DIS_TRet element to the volume face.
